Bennett Marine Lenco to Bennett Conversion Kit – Electric to Hydraulic

Model: V351LK
Conversion Type: Lenco Electric Tabs → Bennett Hydraulic System
Application: Marine Trim Tab Conversion / Upgrade

Upgrade from Electric to Hydraulic Trim Tabs

The Bennett Lenco to Bennett Conversion Kit (V351LK) makes it easy to convert your existing Lenco electric trim tab system to a Bennett hydraulic trim tab setup. This upgrade delivers smoother, more powerful tab response with the proven reliability of hydraulic actuation—ideal for boaters who want better performance and long-term durability.

Smoother, Stronger Trim Tab Control

Hydraulic trim tabs provide consistent pressure and strong lifting force, helping your boat plane faster, ride smoother, and maintain a level attitude in changing sea conditions. This conversion kit lets you keep your existing trim tab planes while upgrading the actuation system.

Direct-Fit Conversion Kit

Designed for straightforward retrofits, this kit includes the components needed to swap out electric actuators for Bennett’s hydraulic system (pump, lines, and hardware as specified by the manufacturer). It’s a clean solution for replacing failed electric systems or upgrading for performance and reliability.

Marine-Grade Reliability

Built with corrosion-resistant, marine-grade components, this conversion kit is designed to handle saltwater exposure, vibration, and continuous use—perfect for offshore and coastal boats.


Key Features

  • Retain Your Hardware: Designed to fit existing Lenco trim tab planes, saving you the cost and labor of replacing the actual stainless steel tabs.

  • Hydraulic Reliability: Eliminates the common "stuck actuator" issues associated with internal electric motors submerged in saltwater.

  • Complete System Swap: Replaces everything from the helm control (optional/dependent on setup) to the actuators with a centralized Hydraulic Power Unit (HPU).

  • Simplified Troubleshooting: With the HPU located inside the boat rather than underwater, maintenance and fluid checks are significantly easier.

  • Legendary Support: Backed by Bennett Marine’s extensive warranty and part availability.
