Abstract
An outboard motor contains an engine. The engine is generally vertically disposed and has a cam chamber positioned on a forward-facing portion of the engine. The cam chamber is defined between a cam cover and a cylinder head assembly. A vapor separator is positioned on the cam cover and protrudes to the outside of the cam cover such that adequate clearance is maintained for a cam shaft arrangement within the cam chamber. The vapor separator has a downwardly facing lubricant outlet that returns lubricant to the cam chamber after the lubricant is separated from the crankcase ventilation gases. A fuel pump is preferably positioned so as to receive lubricant from the lubricant outlet. Moreover, a lubricant fill tube is preferably positioned at least partially higher than the lubricant outlet. In one embodiment, the fill tube is located to a side of the vapor separator while the fuel pump is located below the fill tube.
