Provided is a driving apparatus of a variable pitch propeller having blades, each of which has a pitch angle changed in a rotational direction of a propeller shaft, and a pitch adjuster for adjusting the pitch angle. The pitch adjuster includes blade actuating shafts that are connected to eccentric stubs coupled to lower ends of the blades and are disposed inside the propeller shaft so as to allow linear reciprocation and to push or pull the eccentric stubs, and a power converter that converts a rotating motion of the propeller shaft into a linearly reciprocating motion of the blade actuating shafts.

A variable pitch propeller assembly operatively coupled with an engine and methods for controlling the pitch of a plurality of propeller blades thereof is provided. In one example aspect, the variable pitch propeller assembly includes features for combining overspeed, feathering, and reverse functionality in a single secondary control valve. The secondary control valve is operable to selectively allow a controlled amount of hydraulic fluid to flow to or from a pitch actuation assembly such that the pitch of the propeller blades can be adjusted to operate the variable pitch propeller assembly in one of a constant speed mode, a feather mode, and a reverse mode.

The present disclosure relates to a charging control method and system for a marine propulsion device, and a marine propulsion device. The method includes: acquiring a rotational speed and a regeneration charging power of a motor during a sailing process of a vessel; adjusting the rotational speed to obtain the regeneration charging power corresponding to the adjusted rotational speed, and searching for a power extreme point of the regeneration charging power relative to the rotational speed based on a regeneration charging power varying process; maintaining the rotational speed corresponding to the power extreme point to realize regeneration charging of a battery.

A marine propulsion unit for a marine vessel has a power source for rotating a pitchable propeller around an axis. The pitchable propeller is connected with a first shaft and a second shaft, an adjustment device comprising a first part being connected with the first shaft, a second part being connected with the second shaft, and a movable part. The movable part is configured to be moved between a first position and a second position so as to turn the first part and/or the second part thereby providing a phase shift between the first shaft and the second shaft for pitching and/or folding the pitchable propeller.
