A propulsion system for water vessels comprises a rotor located at the rear end of the vessel body, which rotor rotates inside a shroud to generate a propulsion force, and a stator located behind the rotor for recovering the rotation energy created by the rotor. An unexpected high noise reduction is accomplished because the rotor is mounted on a hollow drive shaft, through which an axle extends which is fixed to the body of the vessel, and which axle support the stator and the shroud that surrounds the rotor, without further supporting devices.
