Abstract
A marine propulsion device includes a drive shaft, a propeller shaft, and a lower case that houses the propeller shaft. In the marine propulsion device, a power generator generates power using a torque of the drive shaft or the propeller shaft, and the generated power is supplied to an electric actuator to drive a driven unit through a first power line, wherein the electric actuator is controlled by a controller. At least a portion of the driven unit, at least a portion of the electric actuator, at least a portion of the power generator, and the first power line are located in the lower case.

A marine propulsion device comprising:
- a drive shaft;
- a propeller shaft;
- a lower case that houses the propeller shaft;
- a power generator to generate power using a torque of the drive shaft or the propeller shaft;
- a driven unit;
- an electric actuator to drive the driven unit;
- a first power line to supply the power generated by the power generator to the electric actuator;
- and
- a controller configured or programmed to control the electric actuator;
- wherein
- at least a portion of the driven unit, at least a portion of the electric actuator, at least a portion of the power generator, and the first power line are located in the lower case.
A marine propulsion device for a marine vessel, the marine propulsion device comprising:
- a drive shaft;
- a propeller shaft;
- a power generator to generate power using a torque of the drive shaft or the propeller shaft;
- a driven unit;
- an electric actuator to drive the driven unit;
- a first power line to supply the power generated by the power generator to the electric actuator;
- and
- a controller configured or programmed to control the electric actuator;
- wherein
- at least a portion of the driven unit, at least a portion of the electric actuator, at least a portion of the power generator, and the first power line are located at a lower level than a waterline in a state where the marine propulsion device is in a tilt-down state and the marine vessel is not sailing.
