ABSTRACT:
An electronic engine speed control particularly adapted for use in marine vehicles for maintaining engine speed in the event the load on the engine changes. The spark timing is adjusted only in the event the engine speed changes without a change in position of throttle valve of the engine. If the speed decreases under these conditions the spark is advanced and if the speed increases the spark is retarded.
