Abstract Propulsion device with outboard waterjet for marine vehicles, which comprises a nacelle (2) which at its interior houses a propeller (3) constituted by a pump (11) actuatable for generating a flow of fluid through the nacelle (2) according to an outflow sense (VF). 5 The nacelle (2) comprises: a front dynamic intake (12) having passage sections substantially increasing according to the aforesaid outflow sense (VF), in a manner such to cause a slowing of the local speed of the fluid and a pressure rise; a rear discharge nozzle (14) having passage sections substantially decreasing in the outflow sense (VF) of the fluid, in a manner such to cause an increase of the local speed of the fluid and a 10 pressure decrease, creating a propulsive thrust jet at the outlet of the discharge nozzle (14).
