Abstract
A snowmobile is provided with an electrical control system for controlling the R.P.M. of the snowmobile engine. Forming part of the control system is a normally open, operator-presence sensing switch arranged in conjunction with a specially mounted throttle control lever such that the switch is closed anytime an operator's thumb is depressing the throttle control lever. The electrical control system is operative when the switch is open to maintain the engine R.P.M. at a value below that necessary for effecting engagement of a speed-responsive variable speed drive connecting an output shaft of the engine with a drive track of the snowmobile, and is operative when the switch is closed to maintain the engine R.P.M. at a value below that considered excessive for the engine and drive components.
