In-Hull & Trolling Motor

Puck Transducer

Models: P72, P76, P78

Applications

• Fiberglass hulls only

• Recommended for high-speed boats

• P72 and P76 accommodate a deadrise angle of 10

° or less

• P78 accommodates a deadrise angle of 10° – 22°

Mounting Location

About Fiberglass Hulls

Since the hull absorbs acoustic energy, transmitting through the

hull reduces the transducer’s performance. Fiberglass hulls are

often cored in places for added strength or to reduce weight. These

cored areas contain balsa wood or structural foam which are poor

sound conductors. Do not locate the transducer over coring.

Placement

CAUTION: Do not mount the transducer near water intake or

discharge openings or behind strakes, fittings, or hull irregularities

that will disturb the water flow.

Choose a location:

• Where the fiberglass is SOLID (no air bubbles are trapped in

the fiberglass resin) and where no coring, flotation material, or

dead air space is sandwiched between the inside skin and outer

skin of the hull.

• Where the hull below the transducer will be in contact with the

water at all times.

• Where the water flowing under the hull is smoothest with a

minimum of bubbles and turbulence (especially at high speeds).

• Away from interference caused by power and radiation sources

such as: the propeller(s) and shaft(s), other machinery, other

echosounders, and other cables. The lower the noise level, the

higher the echosounder gain setting that can be used.

• Where the transducer beam will not be blocked by the keel or

propeller shaft(s).

• Where there is adequate space inside the vessel for

installation.

Record the information found on the cable tag for future reference.

INSTALLATION INSTRUCTIONSOWNER’S GUIDE &

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.

CAUTION: Chose the transducer designed for your

boat’s deadrise angle. Never use adhesive to fill gaps

between the transducer and the hull since this will

greatly reduce the transducer’s performance.

CAUTION: The fiberglass hull below the transducer

must be SOLID. The transducer will not transmit

through coring material such as foam or balsa wood.

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

the cable. This may sever internal connections.

CAUTION: Never use solvents. Paint, sealants,

cleaners, fuel, and other products may contain

solvents that can damage plastic parts, especially

connectors.

IMPORTANT: Please read the instructions completely

before proceeding with the installation. These

instructions supersede any other instructions in your

instrument manual if they differ.
