Transom Transducer Mounting

Before you begin the process of installing the transducer, check your hull to ﬁnd a spot

where you’ll get a smooth water ow along the bottom of the boat. You want to avoid ribs,

rivets, and gouges or scratches in the hull.

To get a true vertical depth reading, the

transducer should be mounted parallel to the

water line. However, a 10° tilt to either side is

acceptable. If the hull is reasonably at with a

dead rise of 10° or less, mount the transducer

along the hull bottom. If dead rise is greater

than 10°, mount the transducer with level

alignment.

1. Assemble the stainless steel brackets to the transducer

using the hardware furnished. Do not tighten until ﬁnal

adjustments are made.

2. Place assembly on transom at selected location with the

front of the transducer extending 1/2” to 5/8” below

the bottom of the boat and with the front part against the

transom. The least amount that the transducer extends

below the bottom is desired. If too low, spray and turbulence will occur resulting

in lost bottom readings.

3. With transducer in place, mark the four slot locations of the transducer mounting

brackets. Drill in center of slot outline using a 9/64” (3.5 mm) drill.

4. Fasten the transducer to the transom using the

#10 x 3⁄4” screws, nuts and washer plates.

5. Before ﬁnal tightening the 4 screws holding the

brackets to the transducer, tip the rear edge

down approximately 1/8” as shown.

6. Tighten all screws.

CAUTION. Do not use any thread locking compound

on the screws. Most products such as Loctite

contain

chemicals that attack and weaken plastics.

IMPORTANT. There should be no gap between the brackets and the transducer. A wide

space between these parts will cause stress on the transducer mounting ears and result in

breakage with time.

When running the cable to the sounder, avoid other wiring on the boat, particularly

ignition and alternator cables. They can be a source of noise on the sounder display.
