In a method for maintenance of a water jet (1) provided in a ship, wherein the water jet (1) comprises a water inlet (2) which is in the form of a closed channel, leading from the sea (18) to a pump housing (3), a blocking body, preferably in the form of an elastic bladder (30), is placed in the water inlet (2), thus blocking off water from the pump housing (3). The pump housing (3) is then opened for maintenance. A blocking body (31), preferably in the form of an elastic ring (31), may also be placed in a water outlet (13) from the pump housing (3). |
