about the Transducer
The transducer is the component of your sounder that transmits sound waves
through the water and receives them to relay the information to your Garmin
echo. With the supplied hardware, you can install the transducer on the
transom of your boat (page 2) or on your trolling motor
assembling the Transducer
1. Insert the rubber washer ➊ and the plastic spacer ➋ into the transducer
➌ at the same time.
Do not add any lubrication to the rubber washer.

2. Pull the cable back and slide the transducer into the mounting bracket ➍.
3. Place a 5 mm flat washer ➎ on the 10-32 x 1.75 in. screw ➏ and insert
the screw through the mounting bracket, transducer, spacer, and rubber
washer.
4. Place a 5 mm flat washer on the exposed end of the 10-32 x 1.75 in.
screw, and fasten it with the 10-32 lock nut ➐.
Do not tighten the 10-32 lock nut. You will adjust the transducer and
tighten the nut after you install the transducer on the boat.

Installing the Transducer on a Transom
Selecting a Transom-mount Location
Select a transom-mount location while considering these guidelines for
optimal performance.
• Mount the transducer as close to the center of the boat as possible.
• Do not mount the transducer behind strakes, struts, fittings, water
intake or discharge ports, or anything that creates air bubbles or
causes the water to become turbulent.
The transducer must be in clean (non-turbulent) water for optimal
performance.
• Do not mount the transducer in the path of the propeller on single-
drive boats.
The transducer can cause cavitation that can degrade the performance
of the boat and damage the propeller.
• On twin-drive boats, mount the transducer between the drives, if
possible.
• Do not mount the transducer in a location where it might be jarred
when launching, hauling, or storing.
Installing the Transom-Mount Hardware
Do not cut the transducer cable. Cutting the transducer cable will void your
warranty.
1. Position the transducer
mount ➊ at the selected
mounting location on the
transom (page 2).
2. Align the transducer parallel
with the water line ➋, and
mark the center location of
each hole on the transducer
mount.
3. Using a / in. (4 mm)

bit, drill the pilot holes
approximately 1 in. (25 mm)
deep at the marked locations,
while taking the following
precautions:
• To avoid drilling the holes too deep, wrap a piece of tape around the
bit at 1 in. (25 mm) from the point of the bit to act as a guide.
• If you are installing the bracket on fiberglass, place a piece of tape
over the pilot-hole location to reduce cracking of the gel-coat.
4. Apply marine sealant to the included 30 mm M5 screws, and loosely
attach the transducer assembly to the transom.
5. Adjust the transducer assembly so that it extends beyond the bottom of
the transom ➌ approximately
(10 mm) on aluminum hulls.
6. Make sure that the transducer is aligned parallel with the water line.
7. Tighten the 10-32 locking nut until it touches the mounting bracket and
then tighten / turn more (do not overtighten).

8. If you would like to route the cable through the transom, choose a pass-
through location well above the waterline ➍ and mark it.
9. Select an option:
• If you have a 4- or 6-pin cable, use a
pass-through hole completely through the transom.
• If you have an 8- or 12-pin cable, use a 1 in. (25 mm) drill bit to drill
a pass-through hole completely through the transom.
