Abstract

PURPOSE: To prolong the life of a water jet propeller by providing a protective part at the end edge of a stator blade for relieving the stator blade of its damage.
CONSTITUTION: The rear end of a suction duct part 5 is connected with an impeller duct part 15 in which stator blades 20 are integrally provided at intervals circumferentially. The center of the stator blades 20 supports the rear end of a driving shaft 11 to which impeller 24 close to the front face of the stator blade 20 is integrally provided. Also, an auxiliary cylinder 25 is provided around the impeller 24, and a protective part 27 is inserted into between the auxiliary cylinder 25 and the impeller duct part 15. The protective part 27 is provided with a rib 30 having a protective cap 31 detachably fittably on the front end edge of the stator blade 20.
