Inside the Hull Transducer Installation

If you choose to mount your transducer inside the hull of your boat, perform the procedures in this section. In-hull mounting generally produces good results in single thickness fiberglass-hulled boats. Humminbird® cannot guarantee depth performance when transmitting and receiving through the hull of the boat, since some signal loss occurs. The amount of loss depends on hull construction and thickness, as well as the installation position and process.

This installation requires slow-cure two-part epoxy. Do not use silicone or any other soft adhesive to install the transducer, as this material reduces the sensitivity of the unit. Do not use five-minute epoxy, as it has a tendency to cure before all the air bubbles can be purged, thus reducing signal strength.

NOTE: In-hull mounting requires an installed and operational control head.

NOTE: The integral temperature probe will not work with in-hull mounting, so you may either want to consider purchasing a Temperature/Speed accessory, a Temp Sensor, or obtaining a different transducer. Humminbird® offers a transducer exchange program to swap the NEW and UNASSEMBLED transducer, accompanied by mounting hardware, for one without an integral temperature probe. Call the Humminbird® Customer Resource Center at 1-800-633-1468 for details, or visit www.humminbird.com for more information.

NOTE: Your transducer may not look exactly like the transducer shown in the illustrations, but it will mount in exactly the same way.
