Lenco Trim Tabs feature quality stainless steel components and a powerful, electrically-driven, ball screw actuator design. Standard-Mount Trim Tab blades are 12-gauge, 304 stainless steel with a 5/8" flared trailing edge and 1/8" diameter hinge pin. Kit includes standard actuators with 5/16" stainless steel bolts. A minimum transom height of 14" is required for installation. Switch kit sold separately. Lenco electric actuators are built around a proven and dependable ball-screw design that is twice as powerful as comparable hydraulic models. More power is complemented by an instant response to helm commands, which means you can correct your boat's trim angle much faster than with hydraulic designs. Actuators are fully submersible.
