To provide a cooling system for a jet propulsion boat in which the quantity of washing water consumed can be reduced and the appearance is improved. The cooling system 40 for a jet propulsion boat forces the engine 15 to be cooled and forces the exhaust system 30 to be cooled by taking a part of a jet of water emitted from the jet pump 20 (shown in Fig. 1) into the intake path 41 as cooling water, and diverging the cooling water taken into the intake path 41 at the diverging duct 50 in an one-way valve unit 42 and flowing it into the engine-cooling flow path 60 and the exhaust- system-cooling flow path 70. The cooling system 40 for a jet propulsion boat is provided with a one-way valve 43 at the midsection of the intake path 41 for enabling cooling water to flow from the intake path 41 to the diverging duct 50 and preventing washing water from flowing from the diverging duct 50 toward the intake path 41.
