ABSTRACT:
To provide a jet propulsion boat in which cooling water is prevented from flowing into the footrest deck or from splashing toward the footrest deck and wherein the occupant can easily recognize the cooling water. A jet propulsion boat includes a vessel body constructed of a lower hull including a ship bottom and an upper hull superimposed thereon. A saddle-riding type seat is provided at the center of the upper surface of the upper hull with footrest decks provided on the left and right of the saddle-riding type seat. An engine and an exhaust system are provided in the interior of the vessel body. The jet propulsion boat includes cooling flow paths for forcing the engine and the exhaust system to be cooled by cooling water. The cooling water discharge ports from the cooling flow paths is provided on the rear surface of the vessel body, except for the portion immediately behind the saddle-riding type seat.
