  • Multi-speed marine propulsion system with automatic shifting mechanism
    Patent number: 5711742
    Abstract: A marine propulsion system, preferably having dual counterrotating propellers, has an automatic multi-speed shifting mechanism such as a transmission. An electronic controller monitors engine parameters such as engine revolution speed and load, and generates a control signal in response thereto, which is used to control shifting. Engine load is preferably monitored by sensing engine manifold air pressure. The electronic controller preferably has a shift parameter matrix stored within a programmable memory for comparing engine speed and engine load data to generate the control signal. The system can also have a manual override switch to override shifting of the shifting mechanism.
