Abstract
A shift interlock system for preventing the starting of an outboard motor when the motor is in gear, the outboard motor having an engine, a starter housing, a starter pulley enclosed by the housing, and a transmission shift lever having a neutral setting, a reverse setting and a forward setting. The system includes a subhousing secured to the starter housing, a plunger mounted in the subhousing for reciprocal linear movement between a retracted position, and an extended position in which the plunger engages the starter pulley to prevent the rotation of the pulley, the plunger being biased in the extended position, and a cam member disposed in the subhousing to pivot between a neutral position in which the cam member overcomes the biasing force and retracts the plunger, and at least one drive gear position in which the cam member permits the extension of the plunger. Also included is an operating link connected to the transmission lever and to the cam member for selectively positioning the cam member to extend the plunger when the transmission lever is in a forward or reverse setting.
