ABSTRACT:
An improved trim-tab control for boats has for each trim tab a yoke movably secured to a frame, a mechanical link between the yoke and the trim tab such that yoke and trim tab move in unison, a lever pivotable mounted with respect to the yoke and having first and second engagement surfaces, and a pair of switches on the yoke positioned for selective engagement with the lever surfaces to actuate a hydraulic device for moving the trim tab in opposite directions. Tab adjustment is carried out by continuing movement of the lever with respect to the yoke, while the yoke moves in response to such adjustment. A scale is secured adjacent to the lever such that the lever position provides visual indication of the trim-tab position.
