Abstract:
A ship propulsion system 11 comprises a first power transmission device 22 that transmits power from an internal combustion engine 20 to a propeller 21, a second power transmission device 32 that transmits power from an electric motor 30 to a propeller 31 and that is mounted to the hull so as to be able to turn up and down independently from the first power transmission device 22, an actuator 33 for causing the second power transmission device 32 to turn up and down, and a control device 4. The control device 4 is configured so as to be able to select a first drive mode in which the internal combustion engine 20 is driven and the electric motor 30 is not driven, and a second drive mode in which the internal combustion engine 20 is not driven and the electric motor 30 is driven. When the first drive mode is selected, the actuator 33 is operated so that the second power transmission device 32 turns up.
