Applications

• Not recommended for boats with large inboard engine(s)
• Not recommended for stepped hull
• 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 sensor from frontal impact only

Mounting Location

CAUTION: Do not mount in line with or near water intake or
discharge openings or behind strakes, fittings, or hull irregularities
that will disturb the water flow.

CAUTION: Avoid mounting the sensor where the boat may be
supported during trailering, launching, hauling, or storage.

• For the best performance, the sensor 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 space above the bracket for it to release and rotate the

sensor upward (see Figure 1).

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

blades are moving downward is preferred.

• Mount the sensor as close to the centerline (keel) of the boat as

possible to ensure the sensor’s face 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 sensor between the drives.

NOTE: Starboard
side of hull where
propeller blades are
moving downward is
preferred.

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: When the boat is placed in the water,

immediately check for leaks around the screws and

any other holes drilled in the hull.
CAUTION: Do not attach the sensor to the bracket

before fastening the bracket to the hull. It is VERY

difficult to separate them if the bracket is unattached.
CAUTION: Never pull, carry, or hold the transducer by

the cable as this may sever internal connections.
CAUTION: Never strike the multisensor with anything

except the palm of the hand. Never strike the

paddlewheel.
CAUTION: Never use solvents. Cleaner, fuel, sealant,

paint, and other products may contain solvents that can

damage plastic parts, especially the transducer’s face.
IMPORTANT: Please read the instructions completely

before proceeding with the installation. These

instructions supersede any other instructions in your

instrument manual if they differ.
