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.
