Abstract
An improved lubricating system for a two-cycle outboard motor having a vertically extending crankshaft. The lubricating system employs a crankshaft driven pump and circulating system that permits pressure lubricating without necessitating elongation of the crankshaft or engine. The engine is enclosed within a cowling and an oil sump is conveniently located within the cowling and is accessible through a cover door of the cowling for replenishment of the oil supply without removal of the cowling.
