Run hard and fast with Lenco High Performance Trim Tabs.Designed for multiple engine applications with limited transom space, this kit's contoured blades allow extra space for engines to turn while reducing cavitation to the props. Blades are robust, 7-gauge, electro-polished, 304 stainless steel for strength and resounding good looks. C-channel mounting brackets facilitate actuator installation. A full back plate adds to overall strength by distributing the load against the transom. Kits come with XD Extreme Duty Actuators factory assembled to the blade and backing plate, which includes a 3 3/4" diameter sacrificial anode. A minimum transom height of 10 1/2" is required for installation.About the actuatorsLenco electric actuators are built around a proven-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 (of course) fully submirsible, with a sealed design and "plug and play" waterproof Deutsch connections, which also help to make installation easy.Key FeaturesFor multiple engine applications with limited transom spaceContoured design allows extra space for engines to turnRobust 7-gauge stainless steel blade constructionTabs include 3 3/4" diameter sacrificial anodeKit ContentsTwo contoured stainless steel trim tab planes with full back platesFour XD Extreme Duty Actuators with 6' lead and Deutsch plugsNOTE:Four Actuator Extension Harnesses (one per actuator) are required and must be purchased separately.
