Abstract
The present invention provides a four-cycle outboard motor ( ),with reduced vibration and improved control stability. The center of gravity is moved forward allowing reduced size. In outboard motor ( ), a crank shaft ( ) is arranged substantially vertically within an engine ( ) so that the rotational force of crank shaft ( ) is transmitted to a propulsion unit via a drive shaft ( ). The shaft centers of crankshaft and drive shaft are arranged either on an axis ( ) of a cylinder constituting engine , or on the centerline of engine ( ), which extends in the fore-aft direction and passes through the shaft center of crankshaft ( ), and in that the shaft center of drive shaft ( ) is arranged offset toward the rear of outboard motor ( ) from the shaft center of crankshaft ( ).
