Boaters can now enjoy a durable and reliable electric trim tab system designed for 17-28 foot boats.

Bennett Marine invented the electric trim tab in 1960 and now Bennett leads the way with a brand new 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 new "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 Bennett strongly recommends hydraulic trim tabs for most applications, electric trim tab systems are suitable for:

  • Trailered boats from 17-28 feet
  • Single actuator use, due to the inability to synchronize two electric actuators on the same tab


What's in the Box:
  • SEA3000 12-volt actuators (2) with 6ft. Wire harnesses and waterproof connectors
  • Stainless steel trim planes (2) and mounting plates
  • 20 Ft Wire Harness with waterproof connectors




Expert Overview

The Bennett BOLT129SML Electric Trim Tab System is designed for marine applications, specifically for trailered boats ranging from 17 to 28 feet. This system provides boaters with a durable and reliable electric trim tab solution. It includes two 12 x 9 stainless steel trim planes and two SEA3000 12-volt actuators, each with a 6ft wire harness and waterproof connectors, plus a 20ft wire harness with waterproof connectors. The actuators feature concealed wiring through the upper hinge, a water-tight black nylon construction, and a high main seal to protect against marine growth and water intrusion. Installation is designed to be straightforward, without requiring disassembly of actuator parts. This system is suitable for single actuator use on a tab, as it does not support synchronization of multiple electric actuators per tab. The BOLT129SML addresses common issues found in older electric systems, offering enhanced protection against environmental factors.
