4 Fishfinder 300C Installation InstructionsMounting the Transducer on a Trolling MotorTo mount the transducer on a trolling motor:1. Slide the large cable tie through the slot on the transducer mount, with the ridges of the cable tie facing up, until equal lengths of cable tieextend on both sides of the mount.NOTE: For cold water, or heavy timber or debris areas, a metal 4–5" (100–130 mm) 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 thetrolling-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 oppositeend 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-tieend 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 turnmore. (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-facingportion (except the cable-tie pocket) of the transducer mount with sealant to avoid accumulating debris.Cable tieFront of the transducerMounting the Transducer on a TransomWhen 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.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, or storing.DO NOT mount the transducer in the path of the propeller on single-drive boats. The transducer can cause cavitation that can degrade theperformance of the boat and damage the propeller. On twin-drive boats, mount the transducer between the drives, if possible.NOTE: DO NOT mount the transducer behind strakes, struts, fittings, water intake or discharge ports, or anything that creates air bubbles or causes thewater to become turbulent. The transducer must be in clean (non-turbulent) water for optimal performance.•••••
