9. Route the cable to the instrument being careful not to tear the
cable jacket when passing it through the bulkhead(s) and other
parts of the boat. Use grommets to avoid chafing. To reduce
electrical interference, separate the multisensor cable from
other electrical wiring and the engine(s). Coil any excess cable
and secure it in place with cable ties to prevent damage.
10.Refer to your echosounder owner’s manual to connect the
multisensor to the instrument.
Checking for Leaks
When the boat is placed in the water, immediately check for
leaks around the screws and any other holes drilled in the hull.
Note that very small leaks may not be readily observed. Do not
leave the boat in the water unchecked for more than three hours.
Operation & Maintenance
Releasing the Multisensor
The multisensor releases easily when it is fastened to the hull.
Give a sharp blow to the bottom of the multisensor using the palm
of the hand. Do not strike the paddlewheel.
Anti-fouling Paint
Aquatic growth can accumulate rapidly on the multisensor’s
surface reducing performance within weeks. Surfaces exposed to
salt water that do not interlock, must be coated with anti-fouling
paint. Use water-based anti-fouling paint only. Never use ketone-
based paint, since ketones can attack many types of plastic
possibly causing damage to the multisensor. Apply paint every 6
months or at the beginning of each boating season.

Cleaning
Clean the transducer’s surface with a Scotch-Brite® scour pad
and mild household detergent taking care to avoid making
scratches. If the fouling is severe, lightly wet sand with fine grade
wet/dry paper.
If the paddlewheel becomes fouled or inoperable, remove it for
cleaning. Remove the multisensor’s cover by inserting the blade
of a small screwdriver under the latch (see Figure 7). Then push
forward while prying upward. Use a small finish nail to push out
the paddlewheel shaft.
Servicing the Paddlewheel
CAUTION: The paddlewheel must be oriented correctly to
measure boat speed.
Orient the short side of the paddlewheel blades as shown in Figure 8.
Slide the shaft through the holes in the housing and paddlewheel
(see Figure 7). Be sure the ends of the shaft are flush with the
housing. Insert the forward tabs of the cover into the housing. Press
down on the back of the cover until the latch snaps into place. (If
necessary, use a small blade screwdriver to depress the tabs on
either side of the latch until they snap under the housing.)
Parts
Replace broken or worn parts immediately. The water-lubricated
paddlewheel bearings have a life of up to 5 years on low-speed
boats [less than 10kn (11MPH)] and 2 years on high-speed
vessels. Purchase parts from you marine dealer or instrument
manufacturer.
