ABSTRACT:
An oil lubrication system for a marine outboard motor including an internal combustion engine. The oil lubrication system includes a series of oil passageways within the cylinder block of the internal combustion engine. The oil passageways are configured such that each cylinder in the internal combustion engine is supplied by its own oil passageway. Each of the oil passageways terminate in an outlet opening. The outlet opening is positioned within the cylinder block such that oil exiting the outlet opening is directed by the force of gravity into contact with a moving component of the internal combustion engine. As the internal components of the internal combustion engine move, oil contacting the components is physically distributed into contact with the bearings.
