Transom-Mount, TRIDUCER

Multisensor

with Integral Release Bracket

Model P58

U. S. Patents: 5,606,253; 5,719,824

Applications

• Not recommended for boats with large inboard engine(s)
• Not recommended for stepped transoms, as multisensor will be

difficult to adjust

• Good operation up to 44kn (50MPH)
• Vertically orients sound beam on hull with deadrise angle up to 22°
• Adjusts to transom angles from 2

–22

• Requires 89mm (3-1/2") of headroom to install
• Bracket protects multisensor from frontal impact only

Tools & Materials

Safety goggles
Dust mask
Screwdrivers
Pencil
Electric drill
Drill bits:

Bracket holes

4mm, #23, or 9/64"

Transom hole (optional)

18mm, 11/16", or 3/4"
21mm or 13/16"

(Furuno only)

24 mm or 15/16" or 1"

(Raymarine only)

Cable clamp holes

3mm or 1/8"

Masking tape
Angle finder
Marine sealant (suitable for below waterline)
Straight edge
Grommets (some installations)
Cable ties
Water-based anti-fouling paint (mandatory in salt water)

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 multisensor where the boat may
be supported during trailering, launching, hauling, or storage.

• For the best performance, the multisensor 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 multisensor upward (see Figure 1).

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

boat as possible to ensure the sensor 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). The starboard
side where the propeller blades are moving downward is
preferred.

• Twin drive boat—Mount the multisensor between the drives.

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 multisensor 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.

Record the information found on the cable tag for future reference
