Abstract
In a marine outboard engine unit driven by a four-stroke-cycle engine, the vertical crankshaft is aft of the cylinders and the camshaft and drives the camshaft via a sprocket-and-chain mechanism, the lower end of the camshaft being coupled to the extension drive shaft which is coupled to the propeller at the lower end of the lower unit, and the carburetor for each cylinder is at the forward part of the engine. By this arrangement, 'oil rise' of the lubricating oil in the engine is prevented when the boat hull, under way, assumes a bow-up attitude, and the speed-reduction ratio from crankshaft to propeller can be reduced, whereby a high-speed, high-power-output engine can be used.
