Abstract
A boat trim control system that includes a pair of trim tabs pivotally mounted to the stern of a boat hull, and an engine responsive to application of electrical ignition power for powering the boat through the water. A pair of fluid actuators extend between the hull and the respective trim tabs for selectively and adjustably moving the tabs between fully extended and fully retracted positions. A fluid drive is responsive to a boat operator for selectively adjusting positions of the trim tabs independently of each other to maintain a desired attitude of the boat hull. Electronic control circuitry is responsive to removal of ignition power from the engine for operating the fluid drive and energizing the actuators for a predetermined time duration so as to move boat trim tabs to the fully retracted positions upon removal of ignition power from the engine.
