Bennett 1812E 18" x 12" Trim Tab System with Euro Rocker Switch

The Bennett 1812E Trim Tab System features 18" x 12" stainless steel trim planes paired with a Euro-style rocker control switch, providing enhanced lift, smoother handling, and precise trim adjustment for small- to mid-size powerboats. The wider 12-inch chord delivers increased control, making this system ideal for boats that need extra stern lift or improved balance under varying load conditions.

Using Bennett’s proven hydraulic trim tab technology, the 1812E system helps reduce bow rise, shorten time to plane, eliminate porpoising, and correct port-to-starboard listing. The included Euro rocker switch offers intuitive, responsive control with a modern, low-profile look at the helm.

Designed for durability in both freshwater and saltwater environments, the Bennett 1812E trim tabs are a reliable upgrade for center consoles, bowriders, and cruisers seeking improved performance and efficiency.

Key Performance Features

  • Euro-Style Rocker Switch (ES2000): This waterproof helm control features an ergonomic design with a positive "click" feel. It is simple to operate and highly reliable, allowing for independent control of each tab to level the boat perfectly.

  • 12-Gauge 304 Stainless Steel: The planes are heavy-duty and designed to resist flexing under high-speed water pressure. Bennett’s interlocking hinge design distributes the load across the entire width of the tab for maximum transom integrity.

  • V351HPU1 Hydraulic Power Unit: The heart of the system is a high-torque pump that generates massive force to hold tabs in position without "creeping," yet is quiet enough to be mounted inside a cabin or bilge locker.

  • Internal Through-Hull Hydraulics: The actuators (A1101A) conceal the hydraulic lines within the upper hinge, passing them directly through the transom. This protects the hoses from UV degradation and physical snags.

  • Modular Serviceability: Every component—from the hydraulic tubing to the internal actuator O-rings—is replaceable, ensuring this system can be maintained indefinitely.
