Abstract
An outboard engine has a power unit, an extension case extending vertically and having its upper end coupled to the power unit, and a propeller mounted on the lower end of the extension case and driven by the power unit. The power unit comprises an internal combustion engine having a vertically extending crank shaft and a cylinder having its axis extending horizontally, and a cover assembly covering the internal combustion engine. The axis of the cylinder is inclined to one side with respect to the axis of the propeller when viewed in plan. The outboard engine can be handled with utmost ease since it can be laid down during storage or shipment without being drained of engine oil.
