Automatic Trim Control for Mid-Size Boats
The Bennett Self-Leveling Trim Tab System SLT10 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.
The SLT10 features a larger blade than the SLT6, making it well-suited to mid-size outboard and stern-drive boats that need more lift authority to get on plane efficiently. Installation is external only — no through-hull work, no control panel wiring required.
What’s Included
- Two (2) 14-gauge 304 stainless steel trim tab blades
- Two (2) self-leveling actuators (lifetime warranty)
- Full stainless steel mounting hardware kit

Parts Desk Insights
Best Use Case: Recommend the SLT10 for customers with mid-size outboard or stern-drive boats (typically 18–24 ft) who are experiencing porpoising, slow planing, or fuel inefficiency and want a no-fuss, switch-free solution. The SLT10 is the step up from the SLT6 — recommend it when the customer’s boat is on the larger or heavier end of the self-leveling range, or when the SLT6 has been tried and found insufficient. It’s a strong entry-level trim tab kit for first-time buyers: external-only installation and no control panel work make it an easy sell. If the customer wants manual or joystick control, upsell to the Bennett JOY1000 Joystick Control. Always confirm boat length, weight, and transom material before recommending blade size.
