Abstract

An outboard engine is supported on a casing which forms an internal discharge chamber having an opening at its top end and a discharge passage with a discharge port near its lower end. The cooling water discharge pipe and an exhaust pipe discharge into the chamber, the cooling water discharge pipe doing so at a lower elevation than the exhaust pipe. A water storage chamber is formed between the casing and the exhaust pipe in heat transfer relationship therewith, and circulation of water is provided to and from the water storage chamber.
