PROBLEM TO BE SOLVED: To provide a jet propulsion boat that can simplify a structure of an exhaust passage.SOLUTION: A jet propulsion boat 1 includes: a hull 2; an engine 5 accommodated in the hull 2; a jet propulsion unit 4 that sucks and jets water with drive power of the engine 5; a first exhaust pipe part 81 connected to an exhaust port 56b of the engine 5; and a catalyst storage part 82 connected to the first exhaust pipe part 81. A part from the first exhaust pipe part 81 to the catalyst storage part 82 is formed integrally.SELECTED DRAWING: Figure 3
