Bennett Marine Trim Plane Assembly, 304 Stainless Steel - Available in 18" x 12" and 30" x 12"

Bennett trim plane assemblies deliver direct OEM-spec replacements for your Bennett trim tab system, built from 304 stainless steel for long-term corrosion resistance in salt and fresh water. Each assembly outfits one side of the boat and includes the trim plane itself, a backing plate, and the hinge needed to mount it to the transom, so you can restore full trim control after damage, corrosion, or an upgrade without sourcing separate parts. Choose the plane size that matches your existing Bennett system to keep hydrodynamic performance and hinge alignment consistent.

Sizes & Options

Match the plane size to your boat's existing Bennett trim tab hardware or OEM spec sheet - the 18" x 12" and 30" x 12" assemblies are not interchangeable, since hinge spacing and plane area are sized to specific tab actuator setups. If you are replacing a single damaged tab, order the same size already installed on the opposite side; if you are outfitting a boat from scratch, confirm sizing against your hull length and Bennett's fitment guidance. Each listing covers one side only, so order two (one of each side, same size) for a complete pair.
