Automatic Trim Control for Smaller Boats
The Bennett Self-Leveling Trim Tab System is designed for boaters who want effortless planing performance without complicated controls or in-hull wiring. The self-leveling actuators automatically return the tabs to a neutral position when power is cut — no switches, no manual reset. Just better performance every time you're on the water.
Ideal for outboard and stern-drive boats up to approximately 20 feet, this system helps you get on plane faster, reduce bow rise, eliminate porpoising, and improve fuel efficiency — all with a straightforward bolt-on installation that requires no through-hull work.

Parts Desk Insights
Best Use Case: Recommend this system for customers with smaller outboard or stern-drive boats (typically under 20 ft) who are experiencing porpoising, slow planing, or fuel inefficiency and want a no-fuss, switch-free solution. It's a strong entry-level trim tab kit for first-time buyers — easy to sell because installation is external only and the self-leveling feature removes the need for any control panel work. If the customer wants manual or joystick control, upsell to the Bennett JOY1000 Joystick Control. Always confirm boat length and transom material before recommending tab size.
