Abstract

A hybrid propulsion system for a marine vessel having a first marine propulsor that propels the marine vessel, a first internal combustion engine that selectively powers the first marine propulsor, and a first electric motor that selectively powers the first marine propulsor. The system also has first and second user input devices and a control circuit that controls operation of the system in at least a first control mode and a second control mode. In the first control mode, the control circuit controls operation of both the first internal combustion engine and the first electric motor based upon actuation of the first user input device. In the second control mode, the control circuit controls operation of the first internal combustion engine based upon actuation of the first user input device and the control circuit controls operation of the first electric motor based upon actuation of the second user input device.

Claims
