Hydraulic Trim Tabs with One-Button Integrated Helm Control — 24" x 12"
The Bennett 219-2412OBI is a complete hydraulic trim tab system built for large, heavy powerboats that require maximum trim authority. The 24" x 12" blade is the widest in the OBI lineup — delivering the surface area needed to effectively control attitude on wide-beam, twin-engine, or heavily loaded hulls where smaller blades simply can’t generate enough lift.
The OBI9000H one-button integrated helm control keeps operation straightforward: a single rocker switch at the helm with automatic tab leveling on release. Hydraulic actuation provides the power and precision to handle the demands of larger vessels in all sea conditions. Everything required for a complete installation is included in the box.

Parts Desk Insights
Best Use Case: Recommend the 219-2412OBI for customers with large powerboats — typically 30 ft and up, or any wide-beam, twin-engine, or heavily loaded hull where 18" blades haven’t been sufficient. The 24" blade is the top of the OBI size range and should be positioned as the solution for customers who have already tried smaller tabs and found them underpowered, or for new builds where the hull spec clearly calls for maximum trim authority. The OBI one-button control keeps the helm clean and simple despite the system’s power. For fully automatic hands-free control, upsell to the Autotrim Pro for Hydraulic Tabs. Always confirm transom width, boat length, and hull weight before finalizing — a 24" blade requires adequate transom real estate.
