Transom-Mount with Release Bracket

Transducer or TRIDUCER

Multisensor

Model P39

U. S. Patents: 5,606,253

Mounting Location

CAUTION: Do not mount in an area of turbulence or bubbles:

near water intake or discharge openings; or behind strakes,

struts, fittings, or hull irregularities

CAUTION: Avoid mounting the transducer where the boat may be

supported during trailering, launching, hauling, or storage.

• For the best performance, the transducer must be in contact

with smooth water. To identify an area of “clean” water, observe

the water flow off the transom while the boat is underway.

• Allow headroom space above the bracket for it to release and

rotate the transducer upward (see Figure 1).

• Mounting on the starboard side of the hull where the propeller

blades are moving downward is preferred.

• Mount the transducer as close to the centerline (keel) of the

boat as possible to ensure the transducer remains in the water

when the boat is turning.

- Single drive boat—Mount at least 75mm (3") beyond the

swing radius of the propeller (see Figure 2).

- Twin drive boat—Mount the transducer between the drives.

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

INSTALLATION INSTRUCTIONSOWNER’S GUIDE &

WARNING: Always wear safety goggles and a dust

mask when installing to prevent personal injury.

WARNING: When the boat is placed in the water,

immediately check for leaks around the screws and

any other holes drilled in the hull.

CAUTION: Never pull, carry, or hold the transducer

by the cable as this may sever internal connections.

CAUTION: Never strike the transducer with anything

except the palm of the hand. Never strike the

paddlewheel.

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.

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

• Not recommended for boats with large inboard engine(s).

• Good operation up to 44kn (50MPH)

• Vertically orients sound beam on hull with deadrise angle up to 30°

• Adjusts to transom angles from 2

° –22°

• Bracket protects transducer from frontal impact only
