ABSTRACT:
A remote shifting system for a marine propulsion unit that employs only forward, neutral and reverse sensing switches for the transmission. A control routine is established whereby when a shift is initiated, the transmission is first moved to its neutral position and then moved to the desired shift position if it is other than a neutral condition. A warning circuit is incorporated for providing a warning and/or protective action in the event a shift does not occur within a predetermined normal time period.
