[origin: EP2591994A1] The device (100) has outer fins (20a-20d) projecting in outward direction from a fore-nozzle (10). Ends (201) of the outer fins are fastened to the nozzle, and other ends (202) of the outer fins are designed as free end (202). End of inner fins (21a-21c) are fastened to an inner wall surface (12) of the nozzle. The outer fins or inner fins are arranged radially to a propeller axis of a propeller of a watercraft and designed as a sweptback fin. The outer fins are arranged in an extension of the inner fins.
