To provide a cooling system for a jet propulsion boat in which the number of components are reduced and the construction is simplified. A cooling system for a jet propulsion boat is a system in which a jet propulsion unit is provided at a rear portion of the vessel body. The jet propulsion unit is driven by the engine to emit a jet of water for propelling the boat. The engine is cooled by flowing a part of the jet of water in the engine-cooling flow path as cooling water. The cooling system for a jet propulsion boat comprises a constantly opened flow path having a constant cross sectional area and a flow regulating valve that opens the valve body when the primary pressure exceeds a prescribed value. The opening of the opened valve body is varied according to the primary pressure in the engine-cooling flow path.
