Bennett TPA129 Trim Plane Assembly, 12 x 9 Inch, Fits 14-18 Foot Boats, Part 6BT500692700

The Bennett TPA129 is a 12 inch by 9 inch trim plane assembly built for one side of the boat, designed to fit boats from 14 to 18 feet in length. The plane is made from high-quality 304 stainless steel, which keeps the assembly strong and rigid even under the repeated stress and saltwater exposure that trim tabs face during regular operation. This is a standard trim assembly, meaning it uses the common Bennett trim plane profile rather than a specialty or reduced-size design.

Each Bennett TPA129 assembly includes everything needed to fit one side of the boat: a trim plane, a backing plate, and a hinge. The backing plate reinforces the transom-mounted plane, while the hinge allows the plane to pivot and adjust the running angle of the boat, helping improve stability and control at speed. Because trim tab planes wear or get damaged individually, the TPA129 is commonly ordered as a single-side replacement rather than requiring a full trim tab system replacement.

With its 12 inch width and 9 inch depth, the TPA129 is sized for smaller to mid-size boats in the 14 to 18 foot range. Boat owners should confirm their existing trim tab plane dimensions and boat size before ordering to ensure the TPA129 is the correct size for their setup.
