The first genuine fully automatic trim tab control system in the world. Integrates a comprehensive array of data, including engine speed, helm position and GPS to calculate the optimum running angle for your boat. Updating data at a rate of twenty-five times per second, the system automatically adjusts your Lenco trim tabs in response to even the fastest-changing conditions. The results include a smoother ride that virtually eliminates porpoising, reduced bow rise for increased forward visibility during hole shots, the best possible fuel efficiency and, by allowing you to concentrate on control of your boat rather than control of the trim tabs themselves, increased safety. System features three programmable automatic operational modes, four automatic settings, and two manual operational modes, with an intuitive helm-mounted keypad for instantaneous fingertip control. Requires Lenco Electric Actuators. Systems include everything you need for a complete installation.
