Abstract
An outboard motor having an oil pan positioned on the underside of the engine, and having an exhaust passage, a water supply passage for cooling water, and a wastewater passage extending down from the engine and passing near the oil pan. The exhaust passage, the water supply passage, and the wastewater passage are molded as a single unit with the oil pan, and provide a simple, lightweight structure that does not result in an increase in the number of parts or assembly man hours necessary for construction. The oil pan is protected from exhaust heat by the water passages, and a flush port to clean the cooling system is easily accessible.
