    • A marine propulsion system, comprising a drive shaft secured to a propeller to rotationally drive the propeller; a motor selectively coupled to the drive shaft to rotate the drive shaft; an electrical energy storage unit coupled to the motor to supply an on-board electrical power supply to the motor, the electrical energy storage unit configured to be recharged by an on-shore electrical power supply; an engine selectively coupled to the drive shaft to rotate the drive shall, the engine not coupled to the electrical energy storage unit for use as a generator to recharge the electrical energy storage unit; and a control system coupled to the motor and to the engine for selecting one of the motor and the engine to rotate the drive shaft. A hybrid marine propulsion method, comprising rotationally driving a drive shaft and propeller using an engine; shifting the engine into neutral; turning on an electric motor by manually activating a motor toggle; disengaging the engine from rotational driving engagement with the drive shaft and engaging the electric motor in rotational driving engagement with the drive shaft; and turning on a fluid sub-system to supply fluid to the drive shaft by manually activating a fluid sub-system toggle.
