Bennett Marine invented the electric trim tab in 1960, and now Bennett leads the way with an electric trim tab system designed to outperform and outlast any electric system on the market.Compared to other electric systems using old technologies designed over twenty years ago, the BOLT Electric combines cutting-edge technology with a robust and water-tight actuator. This “Superior by Design” technology resolves the issues that older systems have with breaking apart and water intrusion caused by design flaws and marine growth.While we strongly recommend hydraulic trim tabs for most applications, electric trim tab systems are suitable for:Trailered boats from 17-28 feetSingle actuator use, due to the inability to synchronize two electric actuators on the same tabFeatures:Wires are concealed and protected through the upper hinge – there are no exposed wires to the marine environmentRobust, water-tight black nylon actuator provides trouble-free operationMain seal located high to protect against marine growth and water intrusion failuresQuieter than any other system on the market – No more scaring the fish away!Installation is fast – no need to disassemble parts of the actuatorControls sold separatelyWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
