摘要： PURPOSE: To eliminate the drop of the output due to the leakage of the jet flow by providing a movable pipe to be turned by the steering on a rear part of a fixed pipe to eject the water jet flow by the rotation of a propeller, and providing a water jet flow leakage preventing member therebetween. CONSTITUTION: A trim ring 22 is fitted to a rear part of a downstream pipe 21b (nozzle pipe) in a vertically turnable manner by bolts 22a, 22b extended in the horizontal direction. A deflector nozzle 23 is fitted to the trim ring 22 turnably in the right-to-left direction to the water level by bolts 23a, 23b extending in the vertical direction. An annular leakage preventing member 25 formed of the elastic material is provided on the trim ring 22. When the deflector nozzle 23 is turned in the vertical or right-to-left direction by the handle operation, the leakage preventing member 25 is pressed to keep the inner surface of the deflector nozzle 23 watertight at a part in which a part of the water jet flows reversely to possibly cause the leakage from the clearance between the deflector nozzle 23 and the trim ring 22.
