Bennett BOLT 18x9 Electric Trim Tab System - Control Switch Required

The Bennett BOLT 18x9 Electric Trim Tab System is a hydraulically powered trim solution engineered for trailered boats in the 17–28 foot range. Bennett Marine developed the electric trim tab concept in 1960 and continues to lead the market with systems that outperform older hydraulic and mechanical designs in responsiveness, durability, and ease of operation. The 18x9 configuration provides the surface area necessary for effective trim and tilt correction on mid-sized recreational and commercial vessels.

This electric trim tab system uses modern hydraulic technology to eliminate bow rise, reduce porpoising, and optimize fuel efficiency across varying sea states and loading conditions. The unit weighs 23.4 lbs and measures 15 x 5 x 25 inches, fitting within standard transom mounting configurations. Operation requires a compatible control switch (sold separately), which allows pilots to adjust trim angle from the helm station. The sealed hydraulic design resists corrosion from saltwater exposure and maintains consistent response in cold and warm climates.

The BOLT 18x9 addresses the core challenge facing operators of center-console and open fishery vessels: maintaining optimal running trim across speeds and payload shifts. Bow-heavy conditions reduce top speed and increase fuel consumption; excessive trim-out risks ventilation and control loss. This electric system responds instantly to helm input, allowing micro-adjustments that manual or older mechanical systems cannot match. Operators frequently report improved stability in following seas, reduced fatigue from running bow-high, and measurable fuel savings on extended offshore runs.

Bennett's BOLT series represents the evolution of trim tab technology for professional and serious recreational boating. Unlike hydraulic-only or manual systems, electric operation puts trim control at your fingertips without crew assistance or complex mechanical linkages. The part number BOLT189 is the industry standard identifier for this 18x9 configuration and is widely recognized by marine technicians and dealers.
