An improved trim tab actuator for a watercraft for permitting the operator to automatically select any of a plurality of steering effects by automatic control of the trim tab. The trim tab is positioned in response to sense steering and watercraft conditions and the operator may also select any of a plurality of modes mapped in response to these conditions.

Trim tab actuator for marine propulsion device

An improved trim tab actuator for an outboard drive for assisting in steering by creating a hydrodynamic steering force immediately upon sensing of a steering input force. The mechanism includes an operator control that permits the operator to select from any of a plurality of preset maps for achieving the optimum trim tab condition.

A trim tab actuator for a marine propulsion device wherein a plurality of watercraft running conditions are sensed and a trim tab is automatically positioned so as to maintain the watercraft in its preset course as dictated by the measured preset condition.

An ignition system spark timing controller having circuits for advancing the time at which the ignition system will produce a sparking potential during the starting of the engine, and for maintaining this advanced spark time for a predetermined time period after the engine has started when the temperature of the engine is below a predetermined temperature level during the starting of the engine. The spark timing controller also includes a circuit for advancing the time at which the ignition system will produce a sparking potential when the speed of the engine is below a predetermined speed level after the engine has started.
