1 – Introduction  
About the FishFinder L365  
The FishFinder L365 is a system that uses sound waves (“sonar”) to  
detect fish and show the bottom of a lake or sea. The system includes a  
transducer and a display unit, connected by a cable. The transducer  
sends high-frequency sound waves down into the water. These sounds  
strike fish, the bottom, or other objects in the water, and return as echoes.  
The FishFinder then interprets these echoes and presents a display.  
The FishFinder L365 can handle many different jobs:  
detect the presence of fish below the boat  
trigger an alarm when fish are found  
measure the depth of the water  
set alarms for minimum and maximum depth  
show the shape of the bottom  
determine whether the seabed is hard or soft  
measure the speed of the boat and the distance traveled  
show the water temperature  
We are sure you will find the FishFinder L365 to be one of the most useful  
devices on your boat.

The installation process has four parts:

Calibrating the display unit  
About the Transducer  
Several different kinds of transducers can be used with this unit. The  
transom-mount style, used most often, and in-hull types are shown in  
Fig. 2-1.  
Besides measuring water depth, the transducers also have two other  
sensors: a paddle wheel which detects the speed of the boat, and a  
sensor for the water temperature. The display unit uses the speed  
information to calculate the distance the boat has traveled. An optional  
transducer, the Sidelooker, detects objects by looking out to the sides of  
the boat.  
Since the transducer is very important to the operation of the FishFinder,  
it is vital that the transducer be mounted correctly. The transducer will  
give the most reliable readings if it looks into water which is smooth and  
undisturbed. If you place the transducer so bubbles or turbulence flow  
across the face of the unit, the system may give inaccurate readings.  
There are three important rules when mounting any type of transducer:  
The transducer should be continuously covered by water when the  
boat is moving. (If the transducer is mounted near the side of the  
boat, it may be exposed when the boat is turning.)  
The transducer should be placed where turbulence or bubbles will not  
pass directly over the face of the unit. Dont place the transducer  
behind any running strakes, intakes, or thru-hull fittings which create  
turbulence.  
The transducer should be mounted where it will not be affected by the  
wash from the propeller(s).

Selecting the Correct Type of Transducer  
Before you begin the installation, double-check to be sure you have the  
correct type of transducer. Each kind of transducer is designed for a  
particular type of use. In this manual we will include detailed mounting  
instructions for the transom-mount transducer. We will also include some  
general information on the other types. For detailed information on these  
other transducers, see the instructions which are packaged with the unit.  
Use a transom-mount transducer if –  
. . . your boat has an outboard or inboard-outboard engine(s), and if youre  
planning to use the Sidelooker option. This type of transducer must be  
mounted ahead of or beside the propeller(s). Do not use this type of  
transducer for a boat with a straight-shaft inboard engine.  
Use a thru-hull transducer if –  
. . . your boat has a straight-shaft inboard engine. This type of transducer  
is installed in a hole drilled through the hull.  
Use an in-hull transducer if –  
. . . you have a high-speed boat or if, for some reason, you cannot use a  
transom-mount or thru-hull transducer.The hull may be no more than 1" thick.

Use a trolling motor transducer if –  
. . . you want to attach the transducer to a trolling motor. (Not recom-  
mended for deep-water operations.)  
Use a Sidelooker transducer if –  
. . . you need a way of searching for fish on either side of the boat. This  
type of transducer is attached to the bracket of the transom-mount  
transducer or to the shaft of the trolling motor.  
Assembling the Transducer Bracket

Positioning the Transom-Mount Transducer  
Begin by finding the best location for the mounting bracket. Here are the  
rules:  
If your boat has one propeller (outboard or inboard-outboard), mount  
the transducer about 18(455 mm) to the side of the centerline of the  
boat. See Fig. 2-3. Choose the side that is on the downstroke of the  
propeller. (This is usually the starboard side of the boat.) This will  
reduce interference caused by air bubbles.  
If the propeller can be turned to steer the boat, allow at least 2" (50  
mm) beyond the swing radius of the propeller. This will prevent the

propeller from damaging the transducer when it is turned. After  
installation, check the clearance by turning the wheel so the propeller  
swings toward the transducer. There should always be a 2(50 mm)  
clearance.  
If your boat has twin propellers (outboard or inboard-outboard), place  
the transducer near the centerline of the boat.  
Do not mount the transducer behind any hull fittings, intakes, or other  
parts which extend from the hull. These may cause turbulence or air  
bubbles.

The bracket has a quick-release mechanism. This may reduce  
damage by allowing the transducer to flip up if it hits any debris or the  
bottom. See Fig. 2-4. Allow enough clearance above the transducer  
so that it can swing upward completely. This is about 10" (254 mm)  
measured from the bottom of the transom.  
If considering the Sidelooker option, look for a mounting location  
where the Sidelooker array will not be blocked by the engine housing  
or other mounted hardware.  
If the boat will be carried on a trailer, be sure the transducer will not  
hit any rollers, bunks or fittings on the trailer.  
Mounting the Transom-Mount Transducer  
1. On a boat with a fiberglass hull, the leading edge of the transducer  
should extend 1/8" (3.2 mm) to 1/4" (6 mm) below the bottom edge of  
the hull. See Fig. 2-5. On an aluminum hull, the transducer should  
extend a bit more 1/4" (6 mm) to 3/8" (9 mm). If the boat will be  
operated at high speeds, the transducer may be mounted closer to  
the centerline of the hull.  
2. The lower surface of the transducer should tilt down toward the rear  
at a slight angle (2° to 5°). The mounting bracket includes a wedge.  
Depending on the angle of the transom on your boat, you may need  
this wedge to get the correct angle for the bottom of the transducer.  
3. Looking at the rear of the boat, be sure the bracket is vertical (perpen-  
dicular to the water line).  
4. Hold the bracket (and the wedge, if used) against the transom and  
trace the positions of the screw slots.  
5. Remove the bracket. See Fig. 2-6. The screws in the outer slots  
should be placed about 1/4" (6 mm) up from the bottom of each slot.  
The screw in the center slot should be placed 1/4(6 mm) down from  
the top. (This will allow you to adjust the bracket up or down a bit.)  
Drill pilot holes 3/4" (19.1 mm) deep. Use a 9/64" (3.6 mm) drill bit.  
To prevent drilling too deeply, wrap masking tape around the drill bit  
about 7/8" (22 mm) from the tip. Drill in only as far as the tape  
marker.  
If you are attaching the bracket to a fiberglass hull, you can minimize  
any surface cracking of the gel coat. Before drilling each pilot hole,  
drill a shallow hole (chamfer) at each location about 1/16" (1.5 mm)  
deep. Use a 1/4" (6 mm) drill bit.

6. Attach the bracket to the hull using the panhead screws with flat  
washers. Before you tighten the screws, apply a good-quality marine  
sealant to the pilot holes. This will protect the hull from water penetra-  
tion. Do not tighten the screws completely yet.  
7. Move the bracket up or down so that the leading edge of the trans-  
ducer has the clearance shown in Fig. 2-5.  
8. Once the bracket is in the correct position, you can tighten the  
screws.  
Mounting the Optional Sidelooker Transducer  
1. The Sidelooker transducer allows the display unit to check the water  
to either side of the boat. This is helpful when you are looking for fish  
or structure near river banks, or under docks or piers.

2. The M78930 Sidelooker transducer is attached to the same mount-  
ing bracket used with the transom-mount transducer. See Fig. 2-7.  
Begin by installing the transom-mount bracket as described earlier.  
3. Remove the two screws and brackets covering the paddlewheel.  
4. Attach the Sidelooker transducer to the top of the transom mounting  
bracket. Use the four panhead screws supplied. The fit should be  
snug, but do not overtighten the screws.

Installation Notes – Thru-Hull Transducer  
Detailed instructions for this installation will be included with the trans-  
ducer. In this section, we will note just a few important points.  
1. Earlier we listed three general rules for placing transducers. All of  
these rules apply when you are mounting a thru-hull transducer. Here  
are some other rules for selecting the best mounting location:  
For planing hulls Install in the flat planing area near the stern.  
Always install forward of the propeller(s) and shaft(s).  
For small displacement hulls Install near the centerline of the hull  
and 1/3 of the way forward from the stern. Always install forward of  
the propeller(s) and shaft(s).  
For large displacement hulls Install near the centerline of the hull  
and 1/3 of the way aft from the bow. Always install forward of the  
propeller(s) and shaft(s).  
For sailboats Install forward of the leading edge of the keel, to one  
side and near the centerline of the hull.  
2. Choose a location where you can easily reach the transducer from  
inside the boat. This will allow you to service the unit. Allow at least  
6" (152 mm) of headroom above the transducer.  
3. When choosing a mounting location, drill a small pilot hole (1/8" or 3.2  
mm) from the inside of the hull. Before you drill the hole, be sure you  
will be able to reach the large nut on the top of the unit, and that there  
will be enough clearance for the cable. If there is a strake or other  
feature on the hull, drill from the outside of the hull instead. (This  
small hole can be filled easily if the mounting location is not suitable.)  
4. The position of the transducer is especially critical on high speed  
boats (capable of more than 20 knots). Check the locations of the  
transducers on similar boats before installing the transducer in your  
own boat. Choose the location which will offer the best performance.  
5. If the bottom of the hull at the mounting location is flat, you can mount  
the transducer directly through the hull. If the hull rises at an angle  
(the deadrise angle) of more than 10°, you must include a mounting  
block or fairing.The transducer must be mounted in a vertical  
position. Attach the fairing block to the hull as firmly as possible. This  
Installation  
11  
Download from Www.Somanuals.com. All Manuals Search And Download.  
fairing block must be able to resist the drag of the water against the  
hull, and must also be completely waterproof.  
6. If the hull of the boat has a core-type hull, you will need to follow  
some special mounting procedures. The core material must be  
protected from any water which may leak from the inside of the boat.  
(If the core material is allowed to remain wet, it may rot and weaken  
the hull.)  
7. When working with the transducer, support it by holding the body of  
the unit or the rings. Do not hang the transducer from the cable.  
8. It is very important to seal the opening around the transducer using a  
high-quality marine sealant suitable for underwater use. After  
installation, do not leave your boat in the water for any amount of time  
without checking for leaks.  
Installation Notes – In-Hull Transducer  
Detailed instructions for this installation will be included with the trans-  
ducer. In this section, we will note just a few important points.  
1. Choose the best mounting location:  
For outboard powerboats Install as far aft as possible  
For inboard/outboard powerboats Install close to the engine(s)  
For inboard powerboats Install forward of the propeller(s) and  
shaft(s)  
For sailboats Install near the centerline of the hull and forward of  
the leading edge of the keel  
2. An in-hull transducer may only be installed in a fiberglass hull which is  
no more than 1" (25 mm) thick. The in-hull transducer may not be  
installed in wood or aluminum hulls.  
3. Use the standard in-hull transducer if it will be installed in a flat part of  
the hull, or a section with no more than 10° of deadrise. Use the  
angled in-hull transducer if the mounting location has up to a 22° of  
deadrise.  
4. Do not try to compensate for the angle of the hull by fairing the epoxy  
adhesive on the face of the transducer.  
5. Use the epoxy supplied with the in-hull transducer, or an equivalent  
epoxy glue. Do not use any other type of adhesive, including silicone  
or RTV adhesive.

Installation Notes – Trolling Motor Transducer  
Both Downlooker and Sidelooker transducers may be installed on a  
trolling motor. See Fig. 2-8.  
Fig. 2-8  
Installing the  
Sidelooker  
Transducer on a  
Trolling Motor  
Detailed instructions for these installations will be included with the  
transducer(s). The Downlooker transducer is mounted on the horizontal  
gear case of the motor. The Sidelooker transducer is attached to the  
vertical support tube. These installations are simple, but it is important to  
keep these points in mind:  
1. Keep the Sidelooker transducer fully submerged. The transducer will  
only produce an image if it is immersed in water.  
2. Keep the Sidelooker transducer clear of weeds or debris.  
3. When the position of the trolling motor is changed, the field of view of  
the Sidelooker also changes. The Sidelooker can be aimed at  
interesting echoes, but can also be positioned so that it is looking  
back at the hull. Be aware of the position of the Sidelooker trans-  
ducer.

included with the transducer. The cable for this transducer uses a Y”  
connector. See the notes on Installing the Transducer Cable.”  
Mounting the Display Unit – Standard Mount  
You may mount the display unit on any flat surface using the bracket  
supplied. See Fig. 2-9. (There is also an optional kit which allows you to  
flush-mount the display in a flat panel or dashboard). Follow these  
instructions if you are using the standard mounting bracket:  
1. The LCDtype display used on this unit is easier to see from certain  
angles. Before selecting a permanent mounting location, make  
temporary power connections and turn on the unit. This will allow you  
to test the visibility of the display from several different angles.  
2. Remove the display unit from the bracket by pressing on the large  
button in the center of the bracket. See Fig. 2-9.  
3. Mount the base of the bracket using the supplied screws.

Dismounting the Display Unit  
See Fig. 2-9. To release the display from the bracket, press and hold  
down the left and right sides. You will hear an audible click,and the  
bracket will slide out.  
Mounting the Display Unit – Flush Mount  
In order to do this installation, you will need the optional flush mounting kit  
(part no. M99-137). See Fig. 2-11.  
1. Select a mounting location on the dashboard or control panel.  
Choose a clear, flat area at least 6" x 6" (152 mm x 152 mm). Be sure  
you will also have at least 6" (152 mm) of clearance behind the area  
where the display unit will be mounted. It is a good idea to drill a  
small pilot hole in the center of the mounting area. Be sure there are  
no hidden electrical wires or other items behind the point where you  
plan to mount the display unit.  
2. A mounting template is supplied with the flush mounting kit. Tape this  
over the selected location on the panel and trace around the edges.  
3. Make the cutout for the display. Drill a series of 1/2" (13 mm) holes at  
the points shown around the edges of the cutout area.

Press the large button in the center of the bracket to separate the  
bracket arms. The display unit is attached to the arms by two screws.  
Each screw is covered by a cap. Locate the small slot beside each  
cap and pry upward using a small screwdriver. Remove the caps,  
then the two screws and the two wave washers. Save these parts in  
case you ever want to use the mounting bracket.  
7. Screw the threaded studs into the holes on the rear of the display unit.  
8. Set the display unit into place to be sure that it will fit correctly.  
Thread the wing-nuts onto the threaded studs to hold the display unit  
in place temporarily.  
9. Once the DC wiring is complete, finish the installation. Hold the  
gasket in place around the opening. Fit the display into the cutout  
again. From the rear, screw the thumbscrews securely onto the  
threaded studs to hold the unit in place.

Installing the Transducer Cable  
A 20 foot length of cable, with the connector attached, is supplied with the  
transducer. During the installation, do not cut the transducer cable or  
remove the connector. Do not try to shorten or splice the cable. The  
transducer cable includes several wires, along with shielding and  
insulation. If the cable is cut, it cannot be repaired. (Cutting the cable  
will also void the warranty.) During installation, if you need to drill any  
holes for the cable, they must be large enough to accept the connector.  
This will allow you to make the installation without cutting the wire.  
1. Route the cable up and over the top edge of the transom. See  
Fig. 2-13. Secure the cable using cable clamps. (These clamps  
are available from your local marine equipment supplier.)  
If you do not want to expose the cable on the deck, you may drill a  
new hole (3/4" or 19 mm) through the transom for the cable. (Re-  
member this hole must be large enough to accept the cable with the  
connector attached. Do not cut the cable!) To seal the opening, use  
a feed-thru cap where the cable passes through the transom.  
2. Run the cable through the interior of the boat. If the transducer cable  
runs near another electrical wire, it may pick up electrical interference  
or noise.To reduce this, try to keep the transducer cable separated  
as far as possible from all other wires. This is especially important  
with wiring for the boats ignition, alternator, or tachometer. Also try to

keep the transducer cable away from the antenna and power cables  
for VHF or FM radios. It is also helpful to keep the transducer cable  
away from the FishFinder power cable. If it is necessary to run the  
transducer cable across any wires, make the crossing at a right angle.  
3. Be careful not to tear the cable jacket when passing it through bulk-  
heads and other parts of your boat. Secure the cables in place using  
tywraps or lacing twine. Coil the extra cable and tie it out of the way.  
4. If the 20 foot transducer cable is not long enough, a 15 foot extension  
cable (4.6 m) is available from your Raymarine dealer (part no. M99-  
139). When you attach the extension cable, be sure that the connec-  
tions are tight and watertight. Use Dow Corning DC-4 or an equiva-  
lent sealing compound to protect the connector assemblies.  
5. At the rear of the display unit, plug in the transducer cable using the  
keyed connector.  
Installing the Transducer Cable – Sidelooker Option  
1. If the installation includes the optional Sidelooker transducer, there  
will be two transducer cables. See Fig. 2-14. The cable from the  
Sidelooker includes a Yconnector.  
2. Plug the cable from the depth transducer into the open end of the Y”  
connector.

Installing theTransducer Cable –  
Installation with Separate Speed andTemperature Sensors  
1. Optional depth-only and speed- and temperature-only transducers are  
available for the FishFinder L365. In this optional configuration the  
separate transducers are connected via a Ytype receptacle cable  
located on the optional speed- and temperature-only transducer cable.  
2. Plug the cable from the depth-only transducer into the receptacle  
connector on the optional speed- and temperature-only transducer.  
The speed- and temperature-only transducer then connects at the  
transducer receptacle of the FishFinder L365. This is shown below in  
Fig. 2-15.

Making the DC Power Connections  
1. The display unit is designed for use on boats with 12V DC power  
systems. (The unit can operate as long as the DC voltage is between  
11.0 and 16V DC.) The display unit can be wired to a negative-ground  
system, or both the negative and positive supply lines may be floating”  
above ground. This unit is not intended for use on boats with  
positive ground.  
20  
Installation  
Download from Www.Somanuals.com. All Manuals Search And Download.  
2. The 5-foot power cable (1.5 m) supplied with the display unit should  
reach the source of DC power. On a small boat, connect the power  
leads directly to the main battery isolation switch or breaker. On a  
larger boat, route the power leads to the DC power distribution panel.  
3. It is very important that you connect the power leads correctly. See  
Fig. 2-16. At the power source, connect the red wire to the positive  
terminal (+), and the black wire to the negative terminal (-). The  
negative terminal may also be called groundor earth.(The display  
unit is internally protected if you accidentally reverse the polarity of  
the power wires.)  
4. Attach the red or positive wire to a 5 amp circuit breaker. If the unit is  
connected directly to the boats battery, include a 2 amp in-line fuse.  
(In-line fuses are available at most marine supply stores.)  
5. To prevent any interference or electrical noise, separate the  
FishFinder power wiring as much as possible from other devices.  
Avoid running the FishFinder power wires near the power wiring for  
any radar, radio, or Loran-C units. If possible, wire the FishFinder  
power wires to a separate circuit breaker.  
6. If you need to extend the power wiring by more than 10 feet, use a  
larger wire size. This will allow the wires to deliver the correct voltage

in spite of the longer wire distance. For runs of 20 to 35 feet (6 to  
10.6 m), use #14 AWG.  
If you extend the power wiring, be sure all electrical connections are  
solid and durable. Soldering is the best way to make these connec-  
tions. Insulate all connections using heat-shrink tubing or electrical  
tape. You may also use crimp connectors or a terminal strip, but be  
sure to use good-quality marine-grade parts.  
7. At the rear of the display unit, plug in the power wires using the keyed  
connector.  
PWR  
8. When you press the  
button, the display unit should turn on. If  
the unit will not turn on and you suspect that you may have reversed the  
power connections, check the DC power lines all the way back to the  
battery. If the polarity is not correct, reconnect the leads properly and  
try again.  
Calibrating the Sensors  
The transducer most often used with this unit includes sensors for boat  
speed and water temperature. These sensors are normally very accurate,  
but you may want to calibrate them. The procedure appears in the section  
on the System Setup Menu (page 55).  
The speed indication on your FishFinder is usually very accurate. How-  
ever, there are some special cases where the speed reading may be high  
or low. This means that the speed of the water past the transducer may  
not be the same speed that your boat moves through the water. The hull of  
the boat may have a shape which channels water past the transducer at a  
speed which is faster or slower than normal.  
1. To calibrate the speed sensor, set up a course between two known  
points. As markers you can use buoys, range markers, or landmarks.  
Measure the length of time the boat takes to cover a known distance.  
2. You may also use locations indicated by a G.P.S. or Loran unit. (If you  
choose this method, remember that these devices measure speed  
over groundor speed over the bottom.Tides, currents, or winds  
can create a difference between the FishFinders speed through  
watermeasurement and the boats speed over ground.Before  
calibrating using a G.P.S. or Loran unit, wait for still water or slack tide  
conditions.  
Installation

3. If the display unit is reading high or low, you can correct for this using  
the entry for Speed Cal.(To reach Speed Cal, go to the System  
Setup display. This is described in Section 4.) The entry for Speed  
Cal is a percentage. An entry of 100equals 100%, meaning that  
there is no correction. If the display unit is producing a low reading,  
use a higher value for Speed Cal. If the display unit is reading high,  
use a smaller number for Speed Cal. You may enter any value  
between 75 and 125.  
4. The temperature sensor is usually very accurate, but you can adjust  
the calibration using the entry for Temp Cal.”

A moment after you first turn on the display unit, the Lamp/Contrast menu  
disappears. The unit then automatically switches to the FishFinder page.  
Figure 3-4 shows a typical display. (The FishFinder page is also called the  
chartor bottom graphdisplay.) As time passes, this display scrolls from  
right to left. The scrolling image becomes a record of the echoes and the  
bottom seen by the FishFinder as your boat moves.  
The images at the right side of the display show the most recent echoes.  
Operating Instructions  
29  
Download from Www.Somanuals.com. All Manuals Search And Download.  
Some of these echoes indicate fish, and others show the bottom. As new  
echoes are received, the FishFinder “draws” a graph of the bottom. The  
bottom graph helps you to tell whether the bottom is rising or falling. It  
also allows you to identify the shape or “structure” of the bottom. This  
can indicate a reef or shipwreck.  
Notice that the scrolling speed of the display does not necessarily match  
the speed of the boat. The scrolling speed of the display is called the  
“chart speed.” You can adjust this using the “System Setup Menu.(See  
Section 4.)  
Many of the items on this display appear in the other modes. Since you are  
likely to use the FishFinder page most often, we will explain all of these  
items here.  
Top of display  
Auto features on  
(AUTO)  
If any of the automatic features are turned on, the “Auto”  
indication will appear here. (These include the automatic  
range, auto sensitivity, and auto zoom features.)  
Auto range on (R)  
The “range” is the maximum depth the unit is set to  
measure. When the auto range feature is on, the  
FishFinder chooses the correct range setting automatically.  
Transducer frequency  
The transducer can use two frequencies - 50 kHz for wide  
coverage, or 200 kHz for a detailed view. You can also set  
the unit to use both frequencies at the same time (“dual  
frequency”). (For more on this, see “Choosing the Fre-  
quency.)  
Auto sensitivity on (S)  
The “sensitivity” controls the ability of the unit to tell the  
difference between echoes of different strengths. A higher  
sensitivity setting makes it easier to see smaller fish, but  
also may pick up background noise. When auto sensitivity  
is on, the FishFinder chooses the correct sensitivity setting  
automatically.

Auto zoom on (Z)  
The zoomcan be used to magnify the image from a small  
section of the water below the boat. (This is used with the  
Zoom display, which we will describe in a moment.) When  
the auto zoom feature is on, the FishFinder automatically  
moves the zoom window up or down to track the bottom.  
Fish symbol on  
When the FishFinder sees a fish, it can show this by  
displaying a fish symbol. When the fish symbol feature is  
turned off, the FishFinder indicates a fish as an arch-  
shaped line on the display. For more information, see the  
section on Fish Indications.”  
Boat symbol This symbol is always turned on. It indicates that the new  
information appears at the right edge of the display, and the  
older information moves toward the left.  
Center of display  
Water surface This symbol (0) shows the depth indicated by the top of  
the display. Usually, this is the level of the surface of the  
water. (If the Zoom feature is turned on, this will show the  
depth of the top of the zoom area.) The depth is shown  
using the same units as the rest of the display. This could  
be feet (FT), fathoms (FA), or meters (M), depending on the  
setting you make in the System Setup display.  
Depth markers  
These markers show depths between the surface and the  
full depth range. In this example, the unit is set for a depth  
range of 100 feet. This means that each of the depth  
markers shows an interval of 20 feet.  
Speed  
This entry shows the speed of the boat through the water.  
From the System Setup display, you can turn this item off or  
change the units used for this display.  
Log/distance This shows how far the boat has traveled since the display  
was turned on, or since the log was last reset. From the  
System Setup display, you can turn this item off or change  
the units used for this display.

Water temperature  
This entry shows the current water temperature at the  
surface of the water. (The reading for water temperature  
can be helpful for finding fish. A particular type of fish will  
often prefer water in a narrow temperature range.) From  
the System Setup display, you can turn this item off or  
change the units used for this display.  
Fish symbol This indicates that the FishFinder sees a fish. Generally,  
the larger the fish symbol appears, the larger the fish. (The  
size of the fish symbol actually depends on a number of  
factors. See the section on Fish Indications.)  
If the fish is detected using the narrow 200 kHz beam, the  
display will show a filled-in symbol. If the fish is detected by  
the wide 50 kHz beam, the display will use a hollow symbol.  
(For more on this, see Choosing the Frequency.)  
Fish depth  
This indicates the depth of the fish shown by the fish  
symbol. This number will be shown using the same depth  
units (feet, fathoms, or meters) you have selected on the  
System Setup display. The fish depth indicator is turned off  
when the fish symbol function is off.  
Bottom of display  
Bottom indication  
This shows the bottom of the lake or sea. You can com-  
pare this to the range depth shown in the lower right-hand  
corner. (In this example, the checkered pattern shows the  
unit is getting a strong echo return from the bottom. See  
the information on the White Line feature in the Setup  
Instructions.)  
Range  
The rangeis the maximum depth the unit is set to  
measure. In this example, this is 100 feet. You can set the  
range manually, or the FishFinder can do it automatically.  
Bottom depth This is the depth of the bottom shown on the display. You  
can select FT (feet), FA (fathoms), or M (meters) using the  
System Setup display. If the FishFinder cant tell how deep  
the water is, the last known depth flashes on the display.  
This will continue until the unit can see the bottom again.

Buzzer symbol  
This symbol shows whether any of the alarms will use the  
buzzer. There are three kinds of alarms: shallow, deep, and  
fish. If one of these alarms is set, it will always present a  
flashing symbol on the display. The Buzzer symbol shows  
whether the alarms will also use the buzzer.  
If the Buzzer setting in the System Setup display is on  
(indicating that the buzzer is enabled for all of the alarms),  
this symbol will appear filled.  
If the Buzzer setting is off (indicating that the buzzer is  
disabled for all of the alarms), this symbol will be open.  
Shallow alarm set  
You can set an alarm to go off if the boat moves into water  
which is shallower than a certain depth. If you set this type  
of alarm, the Sindicator will appear on the display. If the  
alarm is triggered, the Ssymbol will flash. If the buzzer  
has been turned on (in the System Setup display), the  
CLEAR  
buzzer will also sound. To stop the buzzer, press the  
button. The Ssymbol will continue to flash until you move  
into deeper water.  
Deep alarm set  
You can set a different alarm to go off if the boat moves into  
water which is deeper than a certain depth. When this  
alarm is set, the Dsymbol will appear. If the alarm is  
triggered, the Dsymbol will flash. If the buzzer has been  
turned on (in the System Setup display), the buzzer will  
CLEAR  
also sound. To stop the buzzer, press the  
button. The  
Dsymbol will continue to flash until you move into  
shallower water.  
Fish alarm set  
The FishFinder also has an alarm which will sound when-  
ever it detects a fish. When this alarm is set, the fish  
symbol appears at the bottom of the display. If the alarm is  
triggered and the buzzer has been turned on (in the System  
Setup display), the buzzer will sound for a moment.

Before we explain the other pages, there are some general things you  
should know about the operation of the FishFinder.  
Choosing a Frequency  
We said that the FishFinder uses sound waves to seethrough the water  
under the boat. The frequencyis a measure of how fast the sound  
waves change or vibrate.The FishFinder uses sound waves with two  
different frequencies 50 kHz and 200 kHz. Raymarine uses these two  
frequencies because each is better for a particular purpose:  
50 kHz frequency  
Scans a wide area  
Penetrates water well, good for deep water  
200 kHz frequency  
Scans a narrower area, but produces a more detailed view  
Good for seeing fish near the bottom or fish close together  
Better for use in very shallow water  
Dualfrequency (both 50 kHz and 200 kHz at once)  
Has the advantages of both frequencies  
Good depth penetration  
Good detail in display  
Using the Dual 50 kHzsetting, the display is produced using the  
signal from the 50 kHz beam, with additional information from the 200  
kHz beam.  
Using the Dual 200 kHzsetting, the display is produced using the  
signal from the 200 kHz beam, with additional information from the 50  
kHz beam.  
If you are using one of the dual frequency settings, you can get some  
useful information from the fish symbols. If the fish is spotted by the  
narrow 200 kHz beam, the fish symbol will be black or filled-in. If a fish is  
detected by the wide 50 kHz beam, the symbol will be hollow.

Fish Indications  
Even using advanced sonar technology, it is sometimes hard to detect a  
fish in the water. The body of a fish is just a little more dense than the  
surrounding water. There is really nothing very solid for the sound waves  
to bounce off of. The FishFinder L365 is very good at telling the difference  
between a fish and the surrounding water. In fact, Raymarine is the  
leader in this technology.  
When the FishFinder finds a fish, it can be indicated by a fish symbol on  
the display. In general, a larger symbol means a larger fish. This rule is  
not always true, though. Lets say that there are two fish of the same size:  
one is close to the surface, and the other is near the bottom. The fish  
which is close to the surface will have a larger symbol. This is because  
the fish which is closer returns more of the sound waves back to the  
FishFinder.  
Actually, the sound waves are usually reflected by the air sac near the  
center of the fish, and not by the body of the fish. The size of this air sac  
is different for different kinds of fish. This can also affect the size of the  
fish symbols on the display. A fish with a large air sac will produce a large  
fish symbol, while a fish with a small sac will produce a small symbol.  
The symbol also indicates which of the two frequencies was used to locate  
the fish. If the fish was spotted by the wide 50 kHz beam, the symbol will  
appear to be hollow. If the fish was detected by the narrow 200 kHz  
beam, the symbol will be solid.  
If the fish symbol feature is turned off, the FishFinder indicates fish in a  
different way. See Fig. 3-5. An arch-shaped mark on the display usually  
indicates a fish. Again, a larger arch usually indicates a larger fish.  
Several arches together show a school of fish.  
The return from a fish will have a different appearance, depending on the  
frequency used. If a fish is spotted by the wide 50 kHZ beam, the arch will  
be broad. When using the narrower 200 kHz beam, the same fish will  
produce a narrower arch.  
The shape of the arch is also affected by the speed of the boat. If you are  
moving slowly, the arches tend to be longer. If the boat is moving more  
quickly, the arches are short and peaked. If the boat is moving very fast, a  
fish may be indicated by a single vertical line.

Indications  
Bottom Indications  
The bottom usually produces a strong echo, so it is easy for the  
FishFinder to see a lot of detail. The FishFinder can indicate many  
different kinds of bottom conditions. See Fig. 3-6. A hard bottom appears  
as a thin line. A softer bottom or a bottom covered with seaweed will  
produce a wide line, as the sound waves reflect from different layers of the  
bottom. An uneven bottom which is covered with rocks or coral produces  
a complex display like that shown in the last part of Fig. 3-6. The bottom  
image is irregular, with long tailspointing upward. A wreck produces a  
similar image.  
When the White Line feature is turned on, the unit can display even more  
information about the bottom. In Fig. 3-4, the FishFinder is getting a good  
echo from the bottom, so the upper layer of the bottom is shown in a  
checkerboard pattern.

Bottom  
Conditions  
Notice that the lower layer of the bottom is shown as a solid display. This  
indicates a weaker echo. Sometimes this means that the upper layer of  
the bottom is soft. Some of the sound waves may reach through this  
layer, and may be reflected by a more solid layer below. It is also possible  
that the sound waves are making two complete trips - hitting the bottom,  
bouncing off of the bottom of the boat, then reflecting off the bottom again.  
This can happen if the water is shallow, the bottom is hard, or the sensitiv-  
ity is set to a high value.  
Now, lets look at the other main operating displays. From the FishFinder  
display, press the > arrow of the Page control pad.  
Performance Modes  
This unit has two performancemodes which can be used to add to  
the standard FishFinder Page. These are the Zoom and the A-Scope  
Modes. Each presents the raw information from the transducers in a  
special way. To display one of these modes, press the Page key on  
the unit. See Fig. 3-3.

Zoom magnification  
This indicates the amount of zoomor magnification. You  
always set the amount of zoom manually, using one of the  
functions on the Setup display. You can choose an x2 view  
(double the normal display size), x4, x6 or x8 in the series  
of setup screens. See Section 4. You must also select the  
area or windowof the water you want to zoom. See the  
next item.  
Zoom area  
When you turn on the zoom feature, it can only enlarge a  
part of the FishFinder display. You must decide which part  
you want to enlarge. As we said, the right side of the  
display shows the normal FishFinder display. The vertical  
line at the right edge of this display shows the area or  
windowof the water being enlarged.  
When the FishFinder is set for auto zoom, it will choose the  
zoom area automatically. The unit always chooses an area  
of the water which includes the bottom. The unit then  
moves this area up or down to keep the bottom in the  
picture. The auto zoom feature is great for bottom fishing.  
You may also set the zoom area manually. In the series of  
setup screens, select manual zoom. (See Section 4.)  
Once you are back to the zoom display, you can move the  
zoom area up or down (using the and V arrows of the  
Page control pad) to enlarge any selected window.”

On the FishFinder display the bottom graph is drawnafter the FishFinder  
receives several echoes. This has the effect of showing a record of the  
bottom contour. The A-scope displays raw sonar data directly from the  
transducer beam. This gives you a real timeimage of fish and bottom  
structure directly below the transducer. This function is very useful in  
showing the strength of the echo returned from a fish. Stronger fish  
echoes on the A-scope display will appear wider; weaker echoes appear  
as narrow bands closer to the horizontal center of the A-scope image.  
The left section of the A-Scope display shows a section of the normal  
FishFinder display. All of the features are the same. The right section  
shows the A-Scope image.

A-Scope image  
This shows the beam of sound waves extending down from  
the boat, and spreading as it moves through the water. Any  
fish or objects which are positioned under the boat will  
appear on the display. This is a real timedisplay, so you  
can see the fish symbols moving as the fish swim under the  
boat.  
Bottom coverage  
This shows the diameter of the beam of sound waves  
where it meets the bottom. This dimension will be shown  
using the same units as the rest of the display feet (FT),  
fathoms (FA), or meters (M). If the unit is set at 200kHz  
single frequency, the bottom coverage display will reflect  
the narrow (16°) beam of the 200kHz frequency setting. All  
other frequency selections (200kHz dual, 50kHz dual, and  
50kHz single) use the wider (65°) beam for the bottom  
coverage display.

kinds of fishing. It allows you to check for underwater structure along  
the sides of a stream or river, under the edge of a bank or pier, or into  
stumps or weed beds.  
The optional Sidelooker transducer transmits two acoustic beamsone to  
the port side of the boat, and one to the starboard. These are displayed on  
the left and right halves of the Sidelooker Page. See Fig. 3-10.  
Once the Sidelooker feature has been turned on, you can reach the

The Sidelooker Page, like the FishFinder Page, displays a graph or chart.  
The scrolling vertical dashed line represents the centerline of the boat. As  
new Sidelooker echoes are received, the new information appears at the

is no relationship between the chart speed of the FishFinder and the  
speed of the boat. (The speed at which the display moves is set by the  
entry for chart speedin the Setup Menu.)  
When the Fish Symbol feature is turned off, any fish detected will appear  
as vertical marks. These may be slightly arched towards the center of the  
display. The unit can also be set to display fish symbols, but the normal  
fish marks are usually more helpful. The Sidelooker transducer transmits  
at the 200 kHz frequency. If the unit spots any fish while the Fish Symbol

feature is on, they will be indicated by solid fish symbols. (You can turn the  
Fish Symbol feature on or off from the System Setup Menu. See Section 4.)  
Underwater objects such as submerged tree stumps or rocks can also be  
detected by the Sidelooker transducer. These objects usually appear as  
thicker vertical targets. The Sidelooker sounding beam is transmitted very  
close to the surface of the water. In rough or choppy water this turbulence  
may appear on the Sidelooker display as noiseor clutter.The Side-  
looker will also display noise or clutter when your boat travels at high  
speeds or in very shallow water. For best results, use the Sidelooker at  
idle or slow trolling speeds.  
Here are the special items on this display:  
Boat symbol This is pointing forward on the screen to indicate that, on  
the Sidelooker Page, the view is from above, as seen from  
a birds-eye. The boat symbol appears at the top center of  
the Sidelooker View.  
Dashed  
vertical line  
The scrolling vertical line is drawn under, or behind, the  
boat symbol to indicate the division between the information  
produced by the left and the right sidelooker transducer  
elements.  
Side range  
This is the maximum distance the unit will be able to see  
using the current range setting. Remember that the sound  
waves move out at a shallow angle, so this distance is  
measured sideways. See Fig. 3-10. The units used here  
are chosen using the entry for Depth Units in the System  
Setup Menu. If you have selected feet (FT) or fathoms  
(FA), the distance shown here will be measured in feet. If  
you have selected meters (M), the distance shown here will  
be in meters.  
Fish echo mark  
A line or arch-shaped mark shows that the unit has detected  
a fish. In general, a larger mark indicates a larger fish. If the  
fish symbols are turned on, the unit will indicate fish using  
symbols instead. A number beside each symbol shows the  
distance from the boat to the fish. Remember that this  
distance is measured sideways. See Fig. 3-10.

Sensitivity Setting  
Fig. 4-3  
Sensitivity  
Setting  
The sensitivity adjusts the ability of the unit to tell the differences between  
echoes of different strengths. In general, the sensitivity should be as high  
as possible, to detect the fish and show the detail on the bottom. How-  
ever, if the sensitivity is too high, the unit will begin to see bubbles in the  
water, debris, and other “background noise.” Use a higher sensitivity  
setting for deeper water, and a lower setting for shallower water.  
If you adjust the sensitivity while you are looking at the Sidelooker display,  
this will affect the sensitivity for the Sidelooker feature only.  
From the menu item for the range setting, press the V arrow of the Page  
control pad. The next menu item will allow you to set the sensitivity. See  
Fig. 4-3. Use the < and > arrows of the Page control pad to select Auto or

Auto sensitivity  
The FishFinder can be set to select the sensitivity by itself,  
automatically. The unit chooses the sensitivity setting  
which will detect fish, but will also show a minimum of  
background noise. If the amount of background noise  
changes (due to changing depth or water conditions), the  
FishFinder will change the sensitivity to adjust. (You can  
adjust the sensitivity of the unit while it is using Auto  
sensitivity. Once Auto sensitivity is selected, use

You can also set the sensitivity manually. If the amount of  
background noise changes, the FishFinder will not adjust  
for this. If you choose Manual sensitivity, press the V arrow

Figure 4-4 shows how the chart speed setting affects the display. In both  
cases, the unit is showing the same section of the bottom. Using a faster  
chart speed, the display has more space on the display to show this  
section, so it can include more detail. Using a slower chart speed, this  
same information is displayed in a smaller horizontal space.  
A faster chart speed setting shows more detail on the bottom. You will  
probably want to use a faster setting when you are looking for fish.  
A slower chart speed setting shows a longer record of the bottom you  
pass over. Any fish detected will stay on the display longer.  
From the display for the sensitivity setting, press the V arrow of the Page  
control pad. The next menu item will allow you to set the chart speed.  
See Fig. 4-5.  
Chart speed This adjusts the speed at which the information moves

“Frequency” is a measure of how fast the sound waves change or  
“vibrate.” This unit uses sound waves with two different frequencies – 50  
kHz and 200 kHz. For an explanation on the uses of these two frequen-  
cies, see the section on “Choosing a Frequency.”  
From the area of the display for the zoom settings, press the V arrow of  
the Page control pad. The next menu item will allow you to make the  
frequency setting. See Fig. 4-7.  
Frequency  
Use the < and > arrows of the Page control pad to make  
your choice.  
You have four choices here:  
200 kHz, single frequency – The unit will use the narrow 200 kHz  
beam. The fish symbols will be solid.  
50 kHz, single frequency – The unit will use the wider 50 kHz beam.  
The fish symbols will be hollow.  
200 kHz, dual frequency – The unit will use both frequencies, but the  
image on the display will be generated using the information from the  
narrow 200 kHz beam.

50 kHz dual frequency – The unit will use both frequencies, but the  
image on the display will be generated using the information from the  
wider 50 kHz beam.  
If you are using one of the dual frequency choices, some of the fish may  
be revealed by one beam, but not the other. If a fish is detected by the  
narrow 200 kHz beam, the symbol for that fish will appear solid. Any fish  
which are detected by the wider 50 kHz beam will have fish symbols  
which are hollow.

Resetting  
the Log  
The “log” measures how far the boat has traveled through the water. The  
log records the distance traveled since it was last reset. You can reset the  
log at any time using the display shown in Fig. 4-8.  
Distance reading  
The number inside the box shows the distance reading now  
being displayed by the unit. To reset the log to zero, press  
either the < or the > arrows of the Page control pad.

To change one of the items, use the  
and V arrows of the Page control  
pad to move up or down in the display. This will highlight an area on the  
display where the unit is ready to make a change. (This is like the “cursor”  
on a computer.)  
Once you have moved to the correct line, press the < or > arrows of the  
Page control pad to change the entry. When you leave the display, the  
unit will store any changes you have made.  
Simulator  
This unit has a built-in simulator. When the simulator is  
enabled, it presents a realistic display. You can use this  
display to learn about the features of the unit without  
operating your boat. The information on this display is  
generated by the unit itself, and does not come from a  
transducer. When this mode is turned on, you will see the  
word “Simulation” flashing on the display.  
Fish symbol When the unit detects a fish, it can show this using a fish  
symbol. A number above the symbol shows the depth of  
the fish. The size of the symbol is related to the size of the  
fish. In general, the larger the symbol, the larger the fish.  
(For more information, see the section on “Fish Indica-  
tions.”)  
When the fish symbol is turned off, the unit indicates a fish  
by showing an arch-shaped line. See Fig. 3-5. This kind of  
display does not include the depth readings for the fish.  
White line  
This feature controls the way the unit displays strong and  
weak echoes. When the white line feature is turned off, all  
of the echoes are displayed in black. When the feature is  
turned on, strong echoes are displayed using a crosshatch  
(or “checkerboard”) pattern. A weaker return is shown  
using a solid area of black or gray.  
This feature helps to show the difference between the  
strong echo from the bottom and the weaker echoes from  
fish or weeds near the bottom.  
Sidelooker  
This item is used with the optional “Sidelooker” transducer.  
This type of transducer sends sound waves out to the sides  
of the boat. See Fig. 3-10. If you have installed this  
56

transducer, use this line of the display to turn on the  
Sidelooker mode.  
Speed Cal  
This unit can detect and display the speed of the boat  
through the water. It also uses the speed information to  
calculate the distance traveled (the “log”). The item for  
Speed Cal allows you to adjust the speed reading to make  
it match your actual speed through the water. It presents a  
reading in percentage points. A reading of 100% means  
the speed readings from the factory default calibration are  
accurate, and the unit does not need any correction. If the  
unit says that you are moving faster than you really are, you  
can adjust the Speed Cal figure to a smaller number. If the  
unit says that you are moving slower than your actual  
speed, use a larger number for Speed Cal. The setting can  
range between 75 and 125. Use the < and > controls to  
change the value. For more information, see the section on  
“Calibrating the Sensors.”  
Temp Cal  
This unit can display the water temperature. You may want  
to fine-tune the signal from the transducer to get an  
accurate display. The displayed number indicates an offset  
added to the measured temperature. (This offset will be  
measured in °F or °C, depending on the setting used for  
Temp Units.) For example, if the temperature reading on  
the FishFinder display tends to read 2°F too high, you can  
correct for this by setting Temp Cal to -2.0°. The setting  
can range between -9.9° and +9.9°. Use the < and >  
controls to change the value.  
Shallow Alarm You can set an alarm to trigger whenever the boat moves  
into water which is shallower than a limit you set. Use the  
and V controls to move to the line for Shallow Alarm  
and use the > arrow of the Page control pad to turn this  
item on. Once you do this, the display will ask which depth  
you want to use as a limit. Use the < and > controls to set  
the limit you want.To turn this feature off, press the < control  
until the display indicates zero feet, fathoms or meters.  
57  
Setup Instructions

When the shallow alarm is set, the letter “S” will appear in  
the lower left-hand corner of the normal displays. If you  
move into shallow water and trigger the alarm, the letter “S”  
will begin to flash, and the buzzer will sound. Press the  
CLEAR  
button to silence the buzzer. The letter “S” will  
continue to flash until you move into deeper water.  
Deep Alarm An alarm can be set to trigger whenever the boat moves  
into water which is deeper than a preset limit. Use the  
and V controls to move to the line for Deep Alarm and use  
the > control to turn this item on. Once you do this, the  
display will ask which depth you want to use as a limit. Use  
the < and > controls to set the limit you want. To turn this  
feature off, press the < control until the display indicates  
zero feet, fathoms or meters.  
When the deep alarm is set, the letter “D” will appear in the  
lower left-hand corner of the normal displays. If you move  
into deep water and trigger the alarm, the letter “D” will  
CLEAR  
begin to flash, and the buzzer will sound. Press the  
button to silence the buzzer. The letter “D” will continue to  
flash until you move into shallower water.  
Note:You may want to use both the Shallow Alarm and  
Deep Alarm features when you are anchored. Set the limits  
just a bit to either side of your anchor depth. When set this  
way, the unit will trigger an alarm if the anchor drags and  
the boat moves into shallower or deeper water.  
Fish Alarm  
This unit has an alarm which will trigger when the unit  
detects a fish. Use the < and > controls to turn this item on  
or off. The fish alarm feature will work even if the fish  
symbols are turned off.  
When the fish alarm is set, the fish symbol will appear in  
the lower left-hand corner of the normal displays.  
Buzzer  
A buzzer can be set to sound when any of the alarm  
conditions occurs (shallow, deep, or fish alarm). For the  
shallow or deep alarms, the “S” or “D” symbol at the bottom  
CLEAR  
of the screen flashes. By pressing the  
button, you can

silence the buzzer for the current alarm condition. The  
“S” or “D” symbol will continue to flash as long as the alarm  
condition is still present.  
If the alarm condition occurs again, the buzzer will sound  
again. (For example, this would happen if, after a shallow  
alarm you move into deep water, then return to shallow  
water.) You can silence the buzzer again by pressing the  
CLEAR  
button.  
The Buzzer entry in the System Setup display allows you to  
permanently silence the buzzer for all of the alarms. Use  
the < and > controls to turn this item on or off. The buzzer  
symbol at the bottom of the screen will appear hollow.  
Once you do this, if a shallow alarm or deep alarm occurs,  
the “S” or “D” symbol will flash, but the buzzer will not  
sound. You can enable the buzzer again at any time by  
calling up the System Setup display, going to the line for  
Buzzer, and turning the item on again. The buzzer symbol  
at the bottom of the screen will appear solid.  
Each time you press one of the buttons on the display  
panel, the buzzer will “beep.” The buzzer will continue to  
do this, regardless of the setting of the Buzzer option in the  
System Setup display.  
Depth Units This item sets the units used by the depth display. You can  
choose feet (FT), fathoms (FA), or meters (M). Use the <  
and > controls to make your choice.

5 – Maintenance and Troubleshooting  
Periodically check the display unit, cable, and transducer. Be sure all  
components are free of corrosion and are securely mounted. Check all  
cables for signs of chafing or abrasion. Be sure all of the connections to  
the boat’s DC power and ground system are clean and tight.  
Cleaning Instructions  
Always keep the display unit clean. Use a soft, clean cloth to wipe off the  
display panel. Do not use abrasive cleansers, chemical cleaners or  
solvents. Use a glass cleaner or a suitable general-purpose detergent.  
If you operate your boat in salt water, you will have to protect the hull with  
antifouling paint. Use caution when sanding or cleaning the outside of the  
hull near the transducer. Harsh cleaning solvents such as acetone may  
damage the transducer.  
Sea growth can collect quickly on the bottom of the transducer. This can  
reduce the performance in just a few weeks. To prevent this, coat the  
bottom of the transducer with a thin layer of paint. Use only a water-based  
antifouling paint, or a water-based paint specifically designed for transduc-  
ers. Apply it with a brush.  
If your transducer becomes fouled or stops working because of sand or  
sea growth, use a stiff brush to clean it. You may sand the surface with a  
fine-grit wet or dry sandpaper (#320 grade or finer), but this will affect the  
performance of the unit when the boat is moving at higher speeds.  
The paddle wheel mechanism may become jammed by dirt or grit. Work this  
out of the mechanism, then clean the unit with soap and water or alcohol.  
Troubleshooting Suggestions  
If the unit is not working correctly, there may be a simple cause. Before  
you call for service help, please check these points:  
The FishFinder display unit will not turn on –  
1. The unit may actually be operating, but the contrast may have been  
set to the “full light” or “full dark” setting. Turn on the unit by pressing  
PWR  
CLEAR  
the  
and  
buttons at the same time to change all settings to

the factory defaults. See the default settings on page 63.  
2. If the power wiring includes a fuse, it may be blown. Also check the  
circuit breaker or main battery switch.  
3. You may have reversed the power connections. Follow the DC power  
lines all the way back to the battery. The red wire should connect to  
the positive terminal (+) on the battery or power source, and the black  
wire should connect to the negative terminal (-) (also called “ground”  
or “earth”). If the polarity is not correct, reconnect the leads properly  
and check again.  
4. The battery or DC power source may not be producing the correct  
voltage. The FishFinder needs at least 11 volts to operate. If the  
voltage is lower, check for loose or corroded connections, or a  
problem with the power source.  
The display unit “freezes” (temporarily or permanently) –  
1. Check that the display has not been stopped using the Chart Speed  
setting. (If the adjustment bar is moved all of the way to the left, the  
display will freeze.)  
2. A source of electrical “noise” may be interfering with the unit’s  
operation. Both the transducer cable and the power cable for the  
FishFinder should be routed as far as possible from all other wiring on  
the boat.  
To locate the source of the noise, turn on the FishFinder. Next, turn  
on each electrical device on the boat, but just supply power to one  
device at a time. This may reveal the cause of the problem. Move  
the FishFinder, the other unit, or the wiring. A movement of just a few  
inches can make a big difference. If it is necessary to cross any  
wires, make the crossing at a right angle.  
Start the motor in neutral and increase the RPM speed. This can  
reveal a problem with the wiring for the boat’s ignition, alternator, or  
tachometer. It may help to use resistor-type spark plugs or spark plug  
cables on the boat’s motor. You can also try a noise-suppression filter  
on the alternator.  
3. One of the wiring connections may be loose. All of the connections  
should be clean, tight, and insulated. Soldering is the best way of  
making these connections. Protect each connection with a piece of  
shrink-wrap tubing.  
65  
Maintenance and Troubleshooting  
Download from Www.Somanuals.com. All Manuals Search And Download.  
4. The transducer cable may be damaged. Check for any point where  
the wiring may be pinched or bent. Look for signs that water has  
gotten into the cable. If the transducer cable is damaged, the  
transducer and cable should be replaced as a unit. Contact  
Raymarine for instructions.  
The display unit does not see the bottom or fish –  
1. Be sure the display unit is not using the Simulation mode. (If this is  
the case, the word “Simulation” will flash on the display.)  
2. On a unit with the transom-mount transducer, the transducer may  
have “kicked up” because it hit an obstruction. See Fig. 2-4. Move  
the transducer down into the working position.  
3. The unit may be set for Manual sensitivity, and be using a very low  
sensitivity setting. To reset all of the values to the factory defaults, turn  
PWR  
CLEAR  
on the unit by pressing the  
and  
buttons at the same time.  
See the default settings on page 63.  
4. The transducer may not be vertical. Be sure that the transducer is  
aiming straight down, or within 10° of vertical.  
5. If the transducer is an in-hull type, be sure that it is installed correctly.  
The transducer should be “looking” through just one layer of fiber-  
glass hull material, no more than 1" (25 mm) thick. The transducer  
should be firmly attached to the hull using the correct type of adhe-  
sive/sealant.  
6. The face of the transducer may be covered or fouled. Use a stiff  
brush to clean it. You may also sand the surface with a fine-grit wet  
or dry sandpaper (#320 grade or finer), but this will affect the perfor-  
mance of the unit when the boat is moving at higher speeds.  
7. If the FishFinder is using the Auto Sensitivity setting, it may be  
reacting to an increase in electrical “noise.” As the level of noise  
increases, the sensitivity automatically adjusts, and the unit can lose  
its ability to see the bottom or fish. Check for problems with the wiring  
as described in the section on “Display unit freezes.”  
8. The voltage from the power source may be low. This affects the  
transmitting power of the FishFinder. Check the connections as  
described in the section on “The display unit freezes.”  
66  
Maintenance and Troubleshooting

The FishFinder does not display fish arches –  
1. Be sure the Fish Symbol feature is turned off. See the instructions for  
the System Setup display.  
2. The FishFinder will not display arches unless the boat is moving. If  
the boat is stopped, fish will appear on the display as straight lines.  
3. The transducer may not be aimed straight down. In order to display  
complete arches, the transducer must be vertical.  
4. The sensitivity setting may not be high enough. Go to the Setup  
Menu, choose Manual Sensitivity, and increase the sensitivity.  
The display disappears or is unreliable when the boat is moving at  
high speeds –  
1. Increased turbulence around the transducer may be “confusing” the  
unit. Move the transducer to a location where there is less turbulence  
when the boat is moving.  
2. If the FishFinder is using the Auto Sensitivity setting, it may be  
reacting to an increase in electrical “noise. As the level of noise  
increases, the sensitivity automatically adjusts, and the unit can lose  
its ability to see the bottom or fish. Check for problems with the wiring  
as described in the section on “The display unit freezes.”  
The display unit shows lots of background “noise” –  
1. The unit may be set to use the manual sensitivity adjustment, and the  
sensitivity may be set too high. See the information on “Setup  
Instructions.”  
2. The transducer may be mounted incorrectly, or may be fouled. Check  
the mounting as described in Section 2. Clean the transducer as  
described earlier in this section.  
The depth setting flashes often –  
Note: Normally, this indicates that the bottom has moved out of range.  
1. The transducer may not be installed correctly, or the signal may not  
be reaching the display unit. Recheck the instructions in “Mounting  
the Transducer” in Section 2. Check the transducer cable for signs of  
damage. If the cable is damaged, the transducer and cable should be  
replaced as a unit.  
2. The voltage reaching the unit may be low, and this may be affecting  
the transmitting power. Check for problems with the wiring as  
described in the section on “The display unit freezes.”  
Maintenance and Troubleshooting

The speed or log readings are wrong –  
1. The paddle wheel on the transducer may be fouled. Clean the parts  
as described in the section on “Cleaning Instructions.”  
2. Check the speed calibration. Use the item for “Speed Cal” on the  
System Setup display. See the instructions in Section 2.  
Servicing a Thru-Hull Transducer  
If your boat has a thru-hull transducer, you can service it without removing  
the boat from the water. The sensor(s) are mounted in a cylindrical plug  
in the center of the transducer assembly. If necessary, you can remove  
this plug by working from the inside of the boat. The transducer housing  
includes a check valve to minimize the water intrusion when removing the  
insert. A small amount of water will enter the boat. This is normal. Immedi-  
ately after removing the speed insert, place the dummy insert in the  
transducer housing. Do not leave the transducer without the speed or  
dummy insert in place.

Glossary of Terms  
Aft: Near or toward the rear part of the boat (nautical term).  
Background noise: False or meaningless echo returns produced by  
bubbles, water turbulence, or debris  
Bow: The front of the boat (nautical term).  
Cavitation: Air bubbles in the water which affect the readings of a  
transducer. These are normally caused by mounting the transducer  
at an incorrect angle or location.  
Chart Speed: The rate at which echoes scroll across the display.  
Cursor: On a setup display, the place where the unit is ready to make a  
change or enter new information. This point is highlighted. You can  
move up or down the list or display using the  
and V controls.  
Deadrise angle: The slope or angle of the underside of the hull, mea-  
sured in the side-to-side direction.  
Default value: A value or setting which is pre-loaded into the unit at the  
factory.  
Fairing block: A block used when mounting a thru-hull transducer. The  
fairing block shims the transducer to align it on a perfect horizontal  
plane versus the rise of the hull.  
Fathom: A unit of depth equal to 6 feet.  
Frequency: The rate at which a sound source vibrates, or the rate at  
which a sound wave changes.  
Fore: Near or toward the front part of the boat (nautical term).  
Keel: The center of the hull, running from the bow to the stern.  
kHz: Kilo-Hertz” – a measure of frequency (For example, 200 kHz =  
200,000 oscillations per second.)  
Kick-up bracket: A bracket which is installed on the transom of a boat  
and holds the transducer in place. When the transducer strikes an  
obstruction, it is designed to release or kick upout of the water to  
prevent any damage.

Knot: One nautical mile per hour (1.15 statute miles per hour).  
LCD: Liquid Crystal Display- A technology used to produce flat-panel  
displays.  
Nautical mile: 6076 feet  
Port: Left side of the boat, when facing the bow (nautical term).  
PVDF: Poly Vinylidene Fluoride” – A unique polymer plastic that has the  
ability to convert sound waves into electrical impulses. PVDF is used  
in the optional Sidelooker transducer for excellent detection of fish in  
the horizontal direction.  
Range: The depth scale for the unit. The maximum distance the unit will  
be able to see at a particular range setting.  
Sensitivity: The ability of a receiver to distinguish between echoes of  
different strengths. In general, use a higher sensitivity setting for  
deep water, and a lower setting for shallow water.  
Starboard: Right side of the boat, when facing the bow (nautical term).  
Statute mile: 5280 ft.  
Stern: The rear of a boat (nautical term).  
Thermocline: A level in the water where two areas of differing water  
temperature meet. Sometimes a thermocline can reflect sonar waves  
and present a false display.  
Transducer: A device which sends and receives high frequency sound  
waves through the water.  
Transom: The rear-most part of the boats hull, often a flat panel.  
White Line: A feature used to help display fish near the bottom. This  
feature helps to show the difference between weak returns (includ-  
ing fish near the bottom) and strong returns (including the bottom  
itself).  
Zoom: A way of magnifying or enlarging part of the display to give a  
better view of a section of the water.
