Cabela's Transducer Mounting Plates

Transducer Mounting Plates Eliminate unnecessary holes in the transom of your aluminum or fiberglass boat caused by installing sonar transducers and paddle wheels. Maintenance-free, high-density polyethylene plate will not corrode and is pre-drilled for easy installation. Will hold up to four accessories and enables unrestricted placement of transducers. Can be used on either side of the transom. Stainless steel screws included.
The Pro Mounting Plate provides a larger mounting surface, and the screws can be installed above the water line, eliminating leaks. Cut to match any transom angle.
