Assembling the Transducer  
Mounting the Transducer On a Trolling Motor  
1. Slide the large Cable Tie through slot on the Transducer Mount with the ridges of  
the band facing up until equal lengths extend on both sides of the mount. (Note: For  
cold water or heavy timber/debris areas, a metal 4-5” worm gear clamp is recom-  
mended.)  
2. Position the Mount Gasket on the curved top of the Mount.  
3. Place the transducer assembly against the motor body of the trolling motor with the  
front of the transducer pointed away from the trolling motor propeller.  
4. Place the pointed end of Cable Tie through the fastener hole on the  
opposite end and pull through (you will hear clicks) until snug.  
5. Position the transducer so that is will be parallel with the  
bottom when in use and make sure the Gasket is aligned  
properly. Pull the Cable Tie end until tight. Excess may be  
trimmed off if needed. Tighten the 10-32 locking nut until  
it touches the mounting bracket and then tighten 1/4  
turn more (do not overtighten).

Mounting the Transducer On a Transom  
Tool List (not included) - Drill, 3/8" Wrench or Socket, 5/32" and 1/8" Drill Bits,  
Masking Tape, #2 Phillips Screw Driver, Marine Sealant  
1. Position the transom mount at the selected location, making sure the transducer is  
parallel with the water line. Mark the center locations of each hole on the transom  
mount. (see figures to the right)  
Selecting a Transom Mount Location  
Drill Pilot Holes Here  
Level  
For your sonar to operate properly, the transducer has to be located in clean (non-  
turbulent) water. The transducer should be mounted as near the center of the boat as  
possible.  
Do not mount the transducer behind strakes,  
rivet lines, struts, fittings, water intakes or  
discharge ports.  
DO NOT cut the transducer lead, this will void your warranty and may cause the  
unit to not operate at optimal levels.  
2. Using the 5/32" bit, drill the pilot holes approximately 1" (25 mm) deep at the  
marked locations. To avoid drilling the holes too deep wrap a piece of tape around  
the bit 1" from the point of the bit.  
3. Apply Marine Sealant to the 5 x 30 mm screws. Attach the transducer to the transom  
using the 5 x 30 mm screws. Adjust the transducer to extend beyond the bottom  
of the transom approximately 1/8" (3 mm) on fiberglass hulls or 3/8" (10 mm) on  
aluminum hulls. Adjust the transducer to be aligned parallel with the water.  
5. Tighten the 10-32 locking nut until it touches the mounting bracket and then  
tighten 1/4 turn more (do not overtighten).  
6. Place the first cable clamp on the transducer cable approximately one third of the  
distance between the transducer and the top of the transom. Mark the location.  
Using a 1/8" bit, drill a pilot hole approximately 3/8" (10 mm) deep.  
7. Attach the cable clamp using a 4 x 12 mm screw. Coat the screw with marine seal-  
ant before installation. Repeat steps 6 and 7 using the other cable clamp.  
8. Route the transducer cable as needed to the sonar unit. DO NOT CUT THE CABLE.  
Try to avoid routing the cable with electrical wires or other sources of electrical  
interference.  
DO NOT mount the transducer behind strakes, rivet lines, struts, fittings, water  
intake, discharge ports, eroding paint, or anything that creates air bubbles or causes the  
water to become turbulent. It is important that the transducer be as close to the center  
line as possible in calm, non turbulent water for optimal performance. Avoid mounting  
the transducer in locations where the boat may be supported during launching, haul-  
ing, trailering or storage.  
Align with transom  
bottom. Transducer should  
extend 1/8” below fiber-  
glass hulls or 3/8” below  
aluminum hulls.  
Apply marine sealant to all screw  
threads to prevent water from  
seeping into the transom.  
Mount the transducer away from the path of the prop on single drive boats. On  
twin drive boats, mount the transducer between the drives if possible. Do not mount  
the transducer directly in the path of the prop. The transducer can cause cavitation that  
may degrade the boats performance and damage the prop.  
Keep Parallel With Water Line  
Mount the transducer parallel with the  
water line.  
OK  
Make sure the transducer is below  
water level when the boat is on plane  
at high speed.  
Installing the Unit On the Mounting Bracket  
Wiring Harness Installation  
Unit Installation — Selecting a Proper Location  
Testing the Transom Mount Installation  
Choose a location that provides optimal viewing while operating the vessel and  
allows easy access to the units keypad. Select a mounting surface strong enough to sup-  
port the weight of the unit and protect it from excessive vibration or shock. DO NOT  
mount the bracket in a location where the unit will be exposed to extreme tempera-  
ture conditions. When installing the mounting bracket, be sure to allow room for the  
connection/routing of the power cable.  
1. Align the slot on the back of the unit with the long mounting knob and slide in  
place. It may be necessary to adjust the long knob to spread the bracket arms  
apart. (Turn counter-clockwise to widen the bracket arms, clockwise to tighten.)  
2. Adjust the unit angle and tighten the long mounting knob until snug.  
3. Tilt the unit by loosening the long knob on the right side of the bracket assembly.  
4. Rotate the entire bracket by twisting it left or right. (NOTE: You will hear clicks as  
you turn the bracket.)  
The Fishfinder 80 comes with a wiring harness that connects the unit to power and  
the transducer with one easy-to-remove connection. If it is necessary to extend the power  
wires, use 22 AWG wire. DO NOT cut the transducer cable. This will void your warranty.  
If your boat has an electrical system, it may be possible to wire the unit directly to an  
unused holder on your current fuse block. If you are using the boats fuse block, remove  
the in-line fuse holder supplied with the unit. You may also wire the unit direct to the bat-  
tery. CAUTION: The Fishfinder 80 input voltage is 10-18 volts DC. DO NOT exceed  
this voltage as this may damage the unit and void the warranty.  
This test is to be performed after the unit installation. See unit operating instruc-  
tions for additional use information. Since water is necessary to carry the sonar signal,  
the Fishfinder 80 will not function properly with the transducer out of the water. When  
you place your boat in the water CHECK FOR LEAKS around the screw holes that are  
below the water line. DO NOT leave your boat in the water for an extended period of  
time without checking for leaks.  
1. Begin testing the installation at a slow speed. If the sonar appears to be working  
properly gradually increase the boat’s speed observing the sonar’s operation. If the  
sonar signal suddenly is lost or the bottom return is severely degraded, note the  
speed at which this occurs.  
2. Return the boat to the speed the signal was lost. Make moderate turns in both  
directions and see if the signal improves.  
3. If the signal strength improves while turning, adjust the transducer so that it  
extends another 1/8" below the transom of the boat. It may take several adjust-  
ments to eliminate the degradation.  
Mounting the Bracket Assembly  
Tool List (not included) - Drill, Screwdriver (Phillips or Standard), three #8 pan head  
machine bolts with matching nuts and washers and a 5/32” drill bit, OR three #8 pan  
head self-tapping screws and a 1/16” drill bit  
5. Tighten all knobs once the desired viewing angle is obtained.  
Installing the Wiring Harness:  
1. Determine the polarity of the power source using a Test Light or Volt Meter.  
2. Install the Red (+) wire on the Positive fuse holder or battery terminal.  
3. Install the Black (-) wire on the Negative fuse holder or battery terminal.  
4. Install a 2 amp fuse in the fuse holder (fuse block only).  
1. Using the swivel base as a template, mark the location of the three holes which  
will be used to secure the bracket to the mounting surface.  
2. If securing the base with machine bolts, drill three 5/32” holes at the locations  
you marked. OR, If securing the base using self-tapping screws, drill 1/16” starter  
holes at the locations you marked. Starter holes should  
generally be no deeper than half the screw length.  
3. Secure the swivel base with three bolts or screws. DO  
NOT OVERTIGHTEN.  
4. Place the rest of the mount over the swivel base  
and secure with the short knob.  
5. Align the notches on the cable plug and back of the unit. Insert the cable into the  
connector and turn the lock ring counter-clockwise unit it stops.  
Unit Care  
4. If the signal does not improve it may be necessary to move the transducer to a  
different location.  
Cleaning - Clean the unit housing using a cloth lightly dampened with a mild detergent  
solution and then wipe dry. Avoid chemical cleaners and solvents that may damage plas-  
tic components. Do not apply cleaner to electrical contacts on the back of the unit.  
Storage - Do not store the unit where exposure to temperature extremes may occur, as  
permanent damage may result.
