Fitting structure for electrical component part in watercraft

摘要

An electrical component part is fitted to an exterior wall surface of a cooling water passage in a water-cooled engine mounted on a watercraft within a containment structure. The water-cooled engine integrally includes a water tank which forms the cooling water passage and which includes an oil cooler in the inside thereof. The electrical component may be a rectifier connected to a generator and fitted to an outside wall surface of the water tank. A method of cooling the electrical component within the aforementioned containment structure prevents undesirable increases in the temperature of an electrical component part. The water tank may be formed integrally as a single body with an oil tank.
