The invention discloses a propulsion unit for a maritime vessel including a nozzle exhibiting an exchangeable leading edge on the inlet of the nozzle. The propulsion unit (11) for propulsion and maneuvering of a maritime vessel, including a nozzle (12) provided with a sectioned leading edge (21) on inlet of the nozzle (12), which leading edge (21) is formed by sections (21a) of a low-weight non-metallic material, and a front ring (30), which front ring (30) is arranged between main part of the nozzle and the sectioned leading edge (21) and is arranged for providing a fastening point for the sections (21a) of the leading edge (21). In an alternative propulsion unit (11) the nozzle (12) is provided with a sectioned leading edge (21) on inlet of the nozzle (12), which leading edge (21) is formed by sections (21a) of low-weight non- metallic material and at least one section (21a) of metal, where the at least one section (21a) of metal is integrated with the stays (15) in front of the propeller section (13), which stays extend from the periphery of the leading edge (21) and in towards center of the leading edge (21) and are connected with the hub (14) at the other end of the stays (15).
