A propulsion device for a marine vessel includes a driving source including at least one electric motor, a propeller including blades with changeable pitches and rotatable around a central axis of a propeller shaft together with the propeller shaft, a propeller shaft rotation driver to transmit a driving force from the driving source to the propeller shaft and rotate the propeller shaft around the central axis, and a pitch change driver to transmit the driving force from the driving source to the blades and change pitches of the blades. The propeller shaft rotation driver includes a first shaft, and the pitch change driver includes a second shaft closer to a bow side of the marine vessel than the first shaft.
