• 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.
