Abstract:
PROBLEM TO BE SOLVED: To provide a jet propulsion boat which prevents water from entering into an engine when the water flows into an intake box.SOLUTION: A jet propulsion boat includes: a boat hull; an engine housed in the boat hull; a jet pump which generates a jet propulsion force by a driving force of the engine; an intake pipe 46 for supplying air to the engine; an intake box 25; and a filter 35. In the intake box 25, a connection port 45 connected with the intake pipe 46 and an intake port for taking outer air are formed. The filter 35 is disposed in a space 82 forming a part of an internal space 77 of the intake box 25. The filter 35 divides the space 82 into a lower region 88 connected with the intake port and an upper region 89 positioned above the lower region 88 and connected with the connection port 45. The filter 35 purifies air which is taken from the intake port into the internal space 77 and flows toward the connection port 45.SELECTED DRAWING: Figure 15
