Installing Your Fishfinder
4. Wrap the two ends of the cable tie around the motor
body. Place the pointed end of the cable tie through the
fastener hole on the opposite end and pull it through until
it is snug but not tight. (The cable tie clicks when you pull
it.)
5. Position the transducer so that it is parallel with the
bottom when in use, and make sure the gasket is aligned
properly. Pull the cable tie end until tight. Trim off the
excess, if necessary. Tighten the 10-32 locking nut until
it touches the mounting bracket and then tighten 1/4 turn
more. (Do not overtighten.)
6. Route the 20’ (6 m) transducer cable using the supplied
cable ties to secure the cable to the motor shaft. You
can fill the forward-facing portion (except the cable tie
pocket) of the transducer mount with sealant to avoid
accumulating debris.
Mounting the Transducer on a Transom
Tool List
(not included)—drill, 3/8" wrench or socket,
5/32" and 1/8" drill bits, masking tape, #2 Phillips
screwdriver, and marine sealant.
When selecting a transom mount location, consider the
following for optimal performance:
• For your sonar to operate properly, the transducer must
be located in calm water. DO NOT mount the transducer
behind strakes, rivet lines, struts, fittings, water intake,
discharge ports, eroding paint, or anything that creates
turbulence.
• Mount the transducer as close to the center of the boat as
possible.
• DO NOT cut the transducer lead. (This voids your
warranty.)
• DO NOT mount the transducer in locations where it
might be jarred when launching, hauling, trailering, or
storage.
