Summary:A cycloidal marine propulsion unit, including a hollow rotary casing having a central axis and defining a central inner space with an opening at an axial end thereof. A mounting body rotatably supports the rotary casing on a hull of a marine vessel. A rotating arrangement is provided for rotating said hollow rotary casing, while a plurality of blades extend axially from the rotary casing away from the hull. Each blade is mounted for pivotal movement with respect to the rotary casing, about respective blade axes. The rotating arrangement is configured to rotate the rotary casing by a circumference thereof. A blade shaft portion of each blade is at least partly received within the central inner space so as to attach said blade to the rotary casing.
