Selecting a Transom Mount Location For your sonar to operate properly, the transducer has to be located in clean (non-turbulent) water. The transducer should be mounted as near the center of the boat as possible. DO NOT cut the transducer lead, this will void your warranty and may degrade the sonar's operation. DO NOT mount the transducer behind strakes, rivet lines, struts, fittings, water intake, discharge ports, eroding paint, or anything that creates air bubbles or causes the water to become turbulent. It is important that the transducer be as close to the center line as possible in calm, non-turbulent water for optimal performance. Avoid mounting the transducer in locations where the boat may be supported during launching, hauling, trailering, or storage. Mount the transducer away from the path of the prop on single drive boats. On twin drive boats, mount the transducer between the drives if possible. Do not mount the transducer directly in the path of the prop. The transducer can cause cavitation that may degrade the boat's performance and damage the prop. Fishfinder 160C Owner's Manual Installing the Fishfinder 160C > Transducer Installation Do not mount the transducer behind strakes, rivet lines, struts, fittings, water intakes or discharge ports. Mount the transducer parallel with the water line. Make sure the transducer is below water level when the boat is on plane at high speed. Apply marine sealant to all screw threads to prevent water from seeping into the transom.
