Disclosed is a water cooled exhaust assembly for use in association with an internal combustion engine in a marine environment. Inner and outer nested tubes are affixed to a mounting flange to form, in conjunction with an access port in the mounting flange, a cooling water flow channel to provide cooling of exhaust gases fro m the engine. The inner tube is formed with a flattened portion to produce a reduction in exhaust gas turbulence in the flow channel with a consequent increase in heat transfer capability.
