IMPORTANT: Please read the instructions completely before

proceeding with the installation. These instructions supersede any

other instructions in your instrument manual if they differ.

Applications

• Recommended for all hull materials

• Not recommended for hulls less than 9m (30') long

• Not recommended for stepped hulls. Mount an in-hull transducer

• Accommodates a deadrise angle up to 22

Unpacking & Pretest

Remove and discard the packing hardware (rod and 2 nuts) (see

Figure 1). Connect the temperature function to the instrument and

check for the approximate air temperature. If there is no reading

or it is inaccurate, check the connections and test again. If there is

still a problem, return the product to your place of purchase.

Figure 1. Packing hardware

Follow the precautions below for optimal product

performance and to reduce the risk of property

damage, personal injury, and/or death.

WARNING: Boats capable of speeds above 25kn

(29MPH)—You must follow these instructions for a safe

installation. For boats exceeding 35 kn. (40MPH) or when

the instructions cannot be met, mount an in-hull

transducer. At high speeds, the fairing and/or transducer

may break away from the boat.

WARNING: A stuffing tube is required. The stuffing tube

seals the hull forming a water-tight conduit for the cable.

WARNING: The fairing must be installed parallel to the

keel to ensure proper boat handling and water flow under

the transducer.

WARNING: Always wear safety goggles and a dust mask

when installing to prevent personal injury.

WARNING: Immediately check for leaks when the boat is

placed in the water. Do not leave the boat in the water

unchecked for more than three hours. Even a small leak

may allow considerable water to accumulate.

WARNING: Fiberglass hull—The transducer and stuffing

tube must be installed in solid fiberglass, not in coring

CAUTION: Aluminum hull—The stainless steel hardware

must be isolated from an aluminum hull to prevent

electrolytic corrosion.

CAUTION: Steel hull—Follow generally accepted

installation practices.

CAUTION: Never install a metal fitting in a vessel with a

positive ground system.

CAUTION: External mount only. The transducer will

overheat if it is mounted in a hull pocket.

CAUTION: Never pull, carry, or hold the transducer by its

cable. This may sever internal connections.

CAUTION: Never strike the transducer.

CAUTION: Tighten the nylon locking nuts with a torque

wrench using a force not exceeding 27N-m (20ft.-lb.). Do

not over tighten. It may crack the transducer and/or crush

the fairing.

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.
