IMPORTANT : Please read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
CAUTION : NEVER USE SOLVENTS!
Cleaners, fuel, paint, sealants, and other products may
contain strong solvents, such as acetone, which attack
many plastics greatly reducing their strength.

Applications

• Bronze housing recommended for fiberglass or wood hulls.
• Never install a bronze housing in a metal hull because
electrolytic corrosion will occur.
• Never install a metal housing in a vessel with a positive ground
system.
• The hull must be a minimum of 8mm (5/16") thick at the
mounting location.

Sensor Installation

Cored fiberglass hull —Follow separate instructions on page 2.
Choose a location where the sensor will be in contact with the
water at all times.

Hole Drilling

Warning : Always wear safety goggles and a dust mask.
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 21mm or 7/8" 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 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.
