At 42” x 12”, it delivers the surface area needed to lift and level your hull at speed, improving fuel economy, ride comfort, and handling in varying sea conditions.
The assembly arrives ready to install, maintaining the fit and function of the original system without modification.

Parts Desk Insights
Best use case: This assembly is the right call when the trim plane itself is physically damaged, heavily corroded, or missing — rather than when the issue is electrical or hydraulic. If your boat is slow to plane, porpoising, or listing to one side and the existing planes look worn, this is the direct replacement. For EIC system electrical issues, start with the Yamaha Bennett EIC Trim Tab Relay Module 12V before replacing the plane assembly. If you need to protect the new assembly from galvanic corrosion, pair it with an Aluminum Bennett Trim Tab Anode or the Martyr Zinc Bennett Trim Tab Anode Kit. For hydraulic actuator service on the same system, see the Bennett A1103 Upper Hinge – Hydraulic Trim Tab Actuator.
