Abstract
A cooling device of an outboard engine unit includes a cooling water passage for delivering cooling water from a water pump. The cooling water passage branches into a first passageway for cooling a cylinder block and cylinder head of an engine and a second passageway for cooling a case of a supercharger. Thus, the supercharger and the engine can be cooled to and kept at their respective appropriate temperatures.
