Testing The Installation - Garmin XGAR-010-10249-40 Instructions D'utilisation

10. Place a cable clamp on the transducer cable ➎, approximately one third
of the distance between the transducer and the top of the transom or the
pass-through hole.
11. Mark the pilot-hole location for the cable clamp, and, using a
mm) bit, drill a pilot hole approximately
12. Apply marine sealant to the included 12 mm M4 screw, and attach the
cable clamp to the transom.
13. Repeat steps 10–12 to install the other cable clamp approximately two
thirds of the distance between the transducer and the top of the transom or
the pass-through hole.
14. Route the transducer cable to the sounder.
• If you are routing the cable using a pass-through hole, feed it through
the hole you drilled in step 8, and install the cable-entry cover ➍
(page 3).
• If you are not routing the cable using a pass-through hole, route the
cable up and over the top of the transom ➏.
Avoid routing the cable close to electrical wires or other sources of
electrical interference.
Installing the cable-Entry cover
If you routed the cable through the transom after you installed the transducer,
install the cable entry cover to keep water from entering your boat.
1. Place the cable-entry cover ➊ over the hole and the cable,
with the opening pointing downward, and mark the location
of the two pilot holes.
2. Remove the cable-entry cover, and, using a
bit, drill the pilot holes approximately
3. Fill the pass-through hole with marine sealant so that it
covers the cable completely, and that there is excess sealant
around the hole and the cable.
4. Place the cable-entry cover over the hole and the cable, with
the opening pointing downward.
5. Apply marine sealant to the included 12 mm M4 screws, and attach the
cable-entry cover to the transom.
6. Wipe away any excess marine sealant.
Installing the Transducer on a Trolling Motor
Do not cut the transducer cable. Cutting the transducer cable will void your
warranty.
1. Feed the 20 in. (50 cm) cable tie ➊ through the slot on the transducer
mount ➋, with the ridges of the cable tie facing up, until equal lengths
extend on both sides of the mount.
For use in cold water or in areas with heavy timber or debris, use a metal
4–5 in. worm gear clamp (not included) instead of the cable tie.

5. Properly align the gasket between the transducer mount and the body of
the trolling motor, and tighten the cable tie.
If necessary, trim the excess cable tie.
6. Position the transducer so that it will be parallel with the bottom when
in use, tighten the 10-32 locking nut ➍ until it touches the mounting
bracket, and tighten
7. Use the supplied 5
cable to the motor shaft.
If necessary, fill the forward-facing portion (except the cable tie pocket)
of the transducer mount with sealant to avoid accumulation of debris.
8. Route the transducer cable to the installation location of the sounder
while taking the following precautions.
• Avoid routing the cable close to electrical wires or other sources of
electrical interference.
• Make sure that the cable will not become pinched when the trolling
motor is deployed and recovered.

Testing the Installation

➊
Do not leave your boat in the water for an extended period of time without
checking for leaks.
Because water is necessary to carry the sonar signal, the transducer must be
in the water to work properly. You cannot get a depth or distance reading
when out of the water. When you place your boat in the water, check for
leaks around any screw holes that were added below the water line.
Testing the Transom Mount Transducer Installation
When adjusting the depth of the transducer, make the adjustments in
small increments. Placing the transducer too deep can adversely affect the
performance of the boat and put the transducer at risk of striking underwater
objects.
Test the transom mount transducer installation in open water free of
obstacles. Pay attention to your surroundings as you test the transducer.
1. With the boat in the water, turn on the echo.
2. Drive the boat at a slow speed. If the echo appears to be working
properly, gradually increase speed while observing the echo.
If the sonar signal is suddenly lost or the bottom return is severely
degraded, note the speed at which this occurs.
3. Return the boat to the speed at which the signal was lost, and make
moderate turns in both directions while observing the echo.
4. If the signal strength improves while turning, adjust the transducer so that
it extends another
5. Repeat steps 2–4 until the degradation is eliminated.
6. If the signal does not improve, move the transducer to a different location
on the transom.
