ABSTRACT:
A vapor separator for an outboard motor is disclosed. The outboard motor has a cowling and a water propulsion device. An internal combustion engine is positioned in the cowling and arranged to propel the water propulsion device. The engine includes a top and a bottom side. The engine also includes an engine block defining at least one cylinder bore therein. A crankshaft is supported for rotation with respect to the engine block and is located in a first chamber. A camshaft is supported for rotation with respect to the engine block and is located in a second chamber. The engine further includes a lubrication system for the lubrication of the crankshaft and the camshaft. A lubrication collection area is located on the bottom side of the engine for the gravitational collection of engine lubrication fluid from the first chamber and the second chamber. A breather chamber is located on the top side of the engine first passage providing fluid communication between the lubrication collection area and the breather chamber and a second passage in communication between the second chamber and the first passage wherein the second passage is substantially oblique to the first passage.
