Exhaust conduit cooling jacket and thermostat configuration for outboard motors

An exhaust manifold is for an outboard motor having an internal combustion engine. The exhaust manifold has an exhaust conduit that conveys exhaust gas from the internal combustion, and a cooling jacket on the exhaust conduit. The cooling jacket defines a first cooling water passage that conveys coo...

Beschreibung
Zusammenfassung:	An exhaust manifold is for an outboard motor having an internal combustion engine. The exhaust manifold has an exhaust conduit that conveys exhaust gas from the internal combustion, and a cooling jacket on the exhaust conduit. The cooling jacket defines a first cooling water passage that conveys cooling water in a first direction alongside the exhaust conduit, a second cooling water passage that conveys the cooling water from the first cooling water passage in an opposite, second direction alongside the exhaust conduit, and third cooling water passage that is separate from the first and second cooling water passages and conveys spent cooling water from the internal combustion engine to a thermostat.
