Lenco's electro-polishing gives the tabs a beautiful, mirror-like finish and adds ultimate corrosion protection unlike the standard model. Plug & play deutsch connections make installation easy. With their electrically-driven ballscrew design, Lenco Electric Trim Tabs are more reliable and twice as powerful as typical hydraulic trim tabs. More power is complemented by an instant response to helm commands, which means that with Lenco Electric Trim Tabs, you can correct your boat's trim angle much faster than boats equipped with comparatively sluggish hydraulic designs. Lenco's fast-response trim tab actuators are (of course) fully submersible, with a sealed design and "plug and play" waterproof Deutsch connections, which also help to make installation easy. Trim tab blades are robust 12-gauge, 304 stainless steel. Kit includes tim tab blades, actuators and all mounting hardware. Switch Kit sold separately.
