Abstract
A boat control system includes trim tabs mounted on the lower transom of a boat, with an electric trolling motor attached to each tab. The control system controls positioning of the trim tabs within a trim range and within a troll range. If a main engine ignition switch changes from off to on while the trim tabs are within the troll range, the control system automatically moves trim tabs positions out of the troll range, and disables the trolling motors.
