Propulsion unit for vessels which facilitates pitch variation of propeller blades through a characteristic hydraulic actuation device which allows modifying the pitch of propeller blades adjusting it by varying the engine's revolutions. It is also worth highlighting the fact that it includes a position sensor in order to know the position of a yoke in real time and, therefore, the blade pitch. It is even possible to reverse the blade pitch when the vessel goes backwards in order to stop it in a shorter period. The invention is also focused on enabling the replacement of a fixed-pitch propeller propulsion unit already included in a vessel by the propulsion unit of the invention comprising variable-pitch propeller blades.
