A radiator made of a material with excellent thermal conductivity such as an aluminum alloy and having a cooling fluid flow path inside is arranged nearby, and cooling is provided between the water jacket of the engine and the radiator. A liquid circulation path was provided, and a circulation pump was interposed in the circulation path to circulate the coolant, and a small diameter jet water injection hole was bored at an appropriate position of the nozzle toward the radiator. A water-cooled engine cooling system for a small personal watercraft characterized by:
