Mounting the Transducer on a Trolling Motor (Dual Beam Only)

To mount the transducer on a trolling motor:

1.Slide the large cable tie through the slot on the transducer mount (see the illustration on page 9) with the ridges of the band facing up until equal lengths extend on both sides of the mount. (NOTE: For cold water, or heavy timber or debris areas, a metal 4-5" worm gear clamp is recommended.)

2.Position the mount gasket on the curved top of the transducer mount.

3.Place the transducer assembly against the motor body of the trolling motor, with the front of the transducer pointed away from the trolling motor propeller.

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 30-foot (9 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.
