How to attach the sensor to the bracket
1. If the retaining cover near the top of the bracket is closed, open it by depressing
the latch and rotating the cover downward.
2. Insert the sensor's pivot arms into the slots
near the top of the bracket.
3. Maintain pressure until the pivot arms click
into place.
4. Rotate the sensor downward until the bottom
snaps into the bracket.
5. Close the retaining cover to prevent the
accidental release of the sensor when your
boat is underway.
How to route the cable
Route the sensor cable over the transom, through
a drain hole, or through a new hole drilled in the
transom above the waterline.
Never cut the cable or remote the connector; this will void the warranty. 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 19 mm 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 50 mm (2") above the bracket and mark the
mounting hole with a pencil.
4. Position the second cable clamp halfway between the first clamp and the cable
hole. Mark this mounting hole.
5. 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 3 mm or 1/8" bit to drill a hole 10 mm
(3/8") deep. The prevent drilling too deeply, wrap masking tape around the bit 10
mm (3/8") from the point.
7. 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.
8. Position the two cable clamps and fasten them in place. If used, push the cable
cover over the cable and screw it in place.
9. Route the cable to the display unit 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.
