If the transducer lead is too short, extension cables are available from your Garmin dealer. DO NOT cut the transducer lead or any part of the transducer cable, as this will void your warranty. The cable cannot be spliced and connected to any existing (Garmin or non-Garmin) transducer cables. NOTE: DO NOT mount the transducer behind strakes, struts, fittings, water intake, or discharge ports, or anything that creates air bubbles or causes the water to become turbulent. It is important that the transducer is in clean (non-turbulent) water for optimal performance. Apply marine sealant to all screw threads to prevent water from seeping into the transom. �� Mount the transducer parallel with the water surface. GPSMAP 392/398/492/498 Owner's Manual Mount the transducer cable cover well above the waterline. Make sure that the transducer is below the water level when the boat is on plane at high speed. Transducer should extend 1/8" below the fiberglass hull or 3/8" below aluminum hull. Do not mount the transducer directly in the path of the prop. The transducer can cause cavitation that my degrade the boat's performance and damage the prop. 91
