摘要： An exhaust and lubricating system for an outboard motor wherein the outboard motor is provided with an underwater high speed exhaust gas discharge and an above the water low speed exhaust gas discharge. A duck bill type of check valve is provided in the above the water exhaust gas discharge for precluding water from being drawn into the expansion chamber. The engine has a lubricating system with a lubricant reservoir that surrounds the exhaust pipe and is formed integrally with the exhaust pipe. Interconnecting ribs connect the exhaust pipe to the lubricant reservoir and lubricant is returned to the reservoir so that it contacts the wall of the reservoir where the ribs are joined for additional cooling.
