Attach motor mounting bracket to transducer.

2.Slide the adjustable strap supplied with the TMB-S through the slot in the transducer bracket and wrap it around the trolling motor. Po- sition the transducer to aim straight down when the motor is in the water. Tighten the strap securely.

3.Route the transducer cable alongside the trolling motor shaft. Use plastic ties (not included) to attach the transducer cable to the troll- ing motor shaft. Make sure there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the trans- ducer is ready for use.

Transducer Orientation and Fish Arches

If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds.
