Applications

• Bronze housing recommended for fiberglass or wood hulls only

Never install a bronze housing in a metal hull, because

electrolytic corrosion will occur.

• Never install a metal housing in a vessel with a positive ground

system.

Pre-test

After connecting the multisensor to the instrument, spin the

paddlewheel. Check for a speed reading and the approximate air

temperature.

Tools and Materials Needed

Fairing (optional)

Safety goggles

Dust mask

Water-based antifouling paint (mandatory in salt water)

Electric drill

Drill bit: 3mm or 1/8"

Hole saw:

Fiberglass or wood hull: 51mm or 2"

Sandpaper

Mild household detergent or weak solvent (alcohol)

Digital level (installation with fairing)

Band saw (installation with a fairing)

Rasp or power tool (installation with a fairing)

Marine sealant (suitable for below waterline)

Slip-joint pliers

Silicone grease or petroleum jelly (Vaseline

)

Zip-ties

Installation in a cored fiberglass hull:

Hole saw for hull interior: 60mm or 2-3/8"

Cylinder, wax, tape, and casting epoxy (see page 5, #5)

Identify Your Model

The model name is written on the top right corner of the paper tag

affixed to the cable.

Mounting Location

Acoustic Noise

Acoustic noise is always present and these sound waves can

interfere with the operation of the transducer. Background noise

from sources such as: waves, fish, rain, and other vessels cannot

be controlled. However, carefully selecting the multisensor’s

mounting location can minimize the effect of vessel generated

noise from the propeller(s) and shaft(s), other machinery, and

other echosounders. The lower the noise level, the higher the

echosounder gain that can be used.

Placement

Choose a location where:

• The water flowing across the hull is smoothest with a minimum

of turbulence and bubbles (especially at high speeds).

• The multisensor will be continuously immersed in water.

• The transducer beam is unobstructed by the keel or propeller

shaft(s).

• There is a minimum deadrise angle.

• There is adequate headroom inside the vessel for the height of

the housing, tightening the nuts, and removing the valve

assembly and insert.

Caution: Do not mount the multisensor in an area of turbulence or

bubbles such as:

Near water intake or discharge openings

Behind strakes, fittings, or hull irregularities

Behind eroding paint (an indication of turbulence)

Fairing

INSTRUCTIONSINSTALLATION

WARNING: NEVER USE SOLVENTS!

Cleaners, gasoline, 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 directions

supersede instructions in your instrument manual if they

differ.
