The BOLT Electric Trim Tab System combines cutting-edge technology with a robust and water-tight actuator. This resolves the issues that older systems have with breaking apart and water intrusion caused by design flaws and marine growth.

BOLT Electric Trim Tab System Features:

  • Electric Trim Tab Systems for boats between 20 and 23 feet
  • Maximize performance while smoothing out the ride
  • Lifting the stern in proportion to speed, weight distribution, and fuel load changes:
  • Enables you to plane at a much lower speed which improves running inefficiently and saves money
  • Increases operator's sight lines which make for a safer ride, especially in congested waters or foul weather
  • Single actuator per tab - Bennett does not recommend two electric actuators per tab because they cannot be synchronized
  • Robust, water-tight black nylon actuator
  • Main seal located high to protect against marine growth and water intrusion failures
  • Quieter than other systems on the market
  • Installation is fast - no need to disassemble parts of the actuator
  • No wires exposed to the marine environment - wires are concealed and protected through the upper hinge
  • Limited Lifetime Warranty
  • Requires Helm Control (sold seperately)


  • Trim Tab Plane Dimensions: 18" x 9"
  • Power: 12V DC
  • Current Draw: Up to 20 Amps
  • Materials:
    • Trim Tab Planes & Mounting Plates: 304 Stainless Steel
    • Actuators: Upper hinge material made of flexible nylon. Remainder of actuator is made of high impact fiberglass-filled nylon

Note: Image does not represent the true dimensions of the trim tab.

Note: (SALTWATER ONLY) To lower electrolysis, a zinc anode should be attached to the top of each trim tab. Zinc must make direct contact with stainless steel. Do not paint zinc. Do not ground trim tabs to other underwater appendages

Note: These sizing recommendations are based on average performance. Your choice may vary based on power, engine configuration, weight distribution, type of boat, and use. The greater the surface area, angle of deflection and/or speed of the water flowing under the trim tab, the greater the lift. When making a choice between trim tab sizes, remember that the largest trim tabs that will comfortably fit on the transom will be the most efficient. As a rule, choose at least one inch of trim tab span (per side) for every foot of boat length. (Example: 22 foot boat = no less than 24" x 9").
