Sensor Installation
Hole Drilling
Cored fiberglass hull
— Follow separate instructions on page 2.
1. Drill a 3mm or 1/8" pilot hole from inside the hull. If there is a rib,
strut, or other hull irregularity near the selected mounting
location, drill from the outside.
2. Using the appropriate drill bit, cut a hole perpendicular to the
hull from outside the boat.
3. Sand and clean the area around the hole, inside and outside, to
ensure that the marine sealant will adhere properly to the hull. If
there is any petroleum residue inside the hull, remove it with
either mild household detergent or a weak solvent (alcohol)
before sanding.
Record the information found on the cable tag for future reference.

Follow the precautions below for optimal
product performance and to reduce the risk of
property damage, personal injury, and/or death.
WARNING
: Always wear safety goggles and a dust
mask when installing.
WARNING
: Immediately check for leaks when the
boat is placed in the water. Do not leave the boat
unchecked for more than three hours. Even a small
leak can allow considerable water to accumulate.
CAUTION
: Never install a bronze sensor in a metal
hull because electrolytic corrosion will occur.
CAUTION
: Never install a metal sensor on a vessel
with a positive ground system.
CAUTION
: Never pull, carry, or hold the sensor by its
cable; this may sever internal connections.
CAUTION
: Never use solvents. Cleaner, fuel, sealant,
paint, and other products may contain solvents that can
damage plastic parts, especially the sensor’s face.
IMPORTANT
:
Read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
