Abstract
A marine propulsion unit has at least one motor for rotating a pitchable propeller around an axis. The pitchable propeller is connected with a first shaft and a second shaft, the first shaft being rotated by a first power way, the second shaft being rotated by a second power way. The first power way and the second power way are controllable independently of each other so that a first rotation speed (rpm) of the first shaft and a second rotation speed (rpm) of the second shaft can vary.
