INSTALLATION
transducer's angle relative to the hull, use the tapered plastic shim provided. On boats with a 3° angle (stepped
transom and jet boats) use the shim with the tapered end down. If the transom angle is 20° (small aluminium and
Fiberglas boats ) use the shim with the tapered end up. Simply snap the shim into place and, using the straight
edge, sight the angle again to ensure that it is correct.
Note! For other transom angles; fabricate a custom shim from plastic or an oily wood such as teak.
Warning! Do not position the transducer farther down than necessary to avoid increasing drag, spray, and
water noise and decreasing boat speed.
3. Apply a marine sealant to the two screws to prevent water seepage into the transom. Screw the bracket to the
hull. Using the vertical adjustment space available on the bracket slots, slide the transducer up or down to provide
a 6 mm (1/4") projection on fiberglas boats or a 10 mm (3/8") projection on aluminium boats (see Figure 4).
2.5 Cable routing
Route the transducer cable over the transom, through a drain hole, or through a new hole drilled in the transom
above the water line.
Caution! Always wear safety goggles and a dust mask.
1. If a hole must be drilled, choose a location well above
the waterline. Check for obstructions such as trim
tabs, pumps, or wiring inside the hull. Mark the
location with a pencil. Drill a hole through the transom
using a 17 mm (11/16") hole saw or spade bit (to
accommodate the cable cover).
2. Route the cable over or through the transom.
3. On the outside of the hull secure the cable on the
transom using the cable clamps and cable cover (see
Figure 4).
a) Position a cable clamp 50 mm (2") above the bracket
and mark the mounting hole with a pencil. Position
the second cable clamp halfway between the first
clamp and the cable hole and mark this mounting
hole.
b) Open the appropriate slot in the transom cable cover.
Position the cover over the cable where it enters the
hull. Mark the two screw holes.
a) At each of the four marked locations, use a 3 mm or 1/8" drill bit to drill a hole 10 mm (3/8") deep.
