To adjust the sensor’s angle relative to the hull, use the tapered
plastic shim provided. If the bracket has been temporarily fastened
to the transom, remove it, Key the shim in place on the back of the

transom. Screw the bracket to the hull. Do not tighten the screws
completely at this time.

Repeat step 1 to ensure that the angle of the sensor is correct.
Caution: Do not position the sensor farther into the water than
necessary to avoid increasing drag, spray, and water noise and
reducing boat speed.

Cable Routing
Route the sensor cable over the transom, through a drain hole, or
thorough a new hole drilled in the transom above the waterline.

Caution: Never cut the cable or remote the connector; this will void the
warranty.

Warning: 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 19mm or 3/4” bit (to accommodate the connector).

2.
Route the cable over or through the transom.
3.
On the outside of the hull secure the cable against the transom
using the cable clamps. Position a cable clamp 50mm(2”) above the
bracket and mark the mounting hole with a pencil (see Figure 6).

Position the second cable clamp halfway between the first clamp
and the cable hole. Mark this mounting hole.

If a hole has been drilled in the transom, open the appropriate slot
in the transom cable cover. Position the cover over the cable where
it enters the hull. Mark the two mounting holes.

6.
At each of the marked locations, use a 3mm or 1/8” bit to drill a
hole 10mm (3/8”) deep. The prevent drilling too deeply, wrap
masking tape around the bit 10mm (3/8”) from the point.

Apply marine sealant to the threads of the #6 x 1/2” self-tapping
screw to prevent water from seeping into the transom. If you have
drilled a hole through the transom, apply marine sealant to the
space around the cable where it passes through the transom.

9.
Route the cable to the instrument being careful not to tear the cable
jacket when passing it though the bulkhead(s) and other parts of the
boat. To reduce electrical interference, separate the sensor
cable from other electrical wiring and “noise” sources. Coil any
excess cable and secure it in place with zip-ties to prevent damage.
