To mount the dual beam transducer on a trolling
motor:
1. Slide the large cable tie through the slot on the transducer
mount with the ridges of the band facing up until equal
lengths extend on both sides of the mount.
NOTE: For cold water and 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.
NOTE: Leave some slack in the cable to avoid damage while
using the trolling motor.
