    摘要: A marine propulsion unit including a rotary casing rotatable about a central axis A, and blades extending axially from the rotary casing for rotation with the rotary casing about the central axis A, wherein each blade is mounted for pivotal movement about blade axes B. A blade shaft portion of each blade is at least partly surrounded by a blade housing and by a blade portion of each blade is outside the blade housing, wherein the blade housing is releasable attached to the rotary casing, and each blade being supported in the blade housing by means of bearings for the pivotal movement.

    摘要: A watersport propulsion system for a marine watersport vessel includes a drive unit arranged rotatable from a rearward-facing position to a forward-facing position, and vice versa, a control unit being operatively connected with the drive unit. The control unit is configurable in a nominal mode of operation and in a watersport mode of operation. The control unit is configured to operate the drive unit in the forward-facing position when in the watersport mode of operation and in the rearward-facing position otherwise.

    摘要: A marine propulsion system for marine vessel includes at least one battery configured to power a vessel load, a plurality of marine drives, and a control system. Each of the plurality of marine drives includes an engine, an alternator driven by the engine to charge the battery, and a propulsor selectively driven by the engine to propel the marine vessel. Each of the plurality of marine drives is configured to operate in a propulsion mode in which the engine is operated to rotate the propulsor to propel the marine vessel in a generator mode in which the engine is operated to charge the battery while the marine vessel remains stationary. The control system is configured to select a subset of the plurality of marine drives and then to operate the subset of marine drives in the generator mode to charge the battery while the marine vessel remains stationary.
