摘要： An air-cooled internal combustion engine includes a cylinder block having a plurality of cylinder bores disposed in parallel to each other, a cylinder head secured to an upper portion of the cylinder block, a crankshaft, two camshafts disposed in a parallel, juxtaposed relationship to each other so as to extend perpendicularly to a forward and backward direction of a vehicle on which the engine is mounted at an upper portion of said cylinder head and positioned on front and rear sides of the engine relative to each other, and a camshaft driving mechanism for transmitting rotational driving force of the crankshaft to the camshafts. A cooling space into which wind can be introduced is formed below that one of the camshafts which is positioned on the front side of the engine. The entire cylinder head is thus cooled efficiently, including portions corresponding to the cylinders disposed at intermediate positions of the engine.

An engine is mounted on a watercraft body with a crankshaft of the engine extending along the longitudinal direction of the watercraft body and a shaft of a jet pump is coupled via a coupler to a rear end of the crankshaft in such a manner so as to be disposed on an extension of the crankshaft. A coupler cover is provided for covering the coupler, and piping for cooling water, which is in communication with the jet pump, is fixed onto the coupler cover. A turbo-charger is disposed over the coupler, and the piping is fixed on the coupler cover at a position between the coupler cover and the turbo-charger.

A first biasing mechanism is configured to apply a clamping force to the clutch discs. A cam mechanism is configured to adjust the clamping force in accordance with the rotational driving force. A second biasing mechanism is configured to generate a biasing force to separate the clutch discs away from one another and to weaken the clamping force. The cam mechanism is configured to apply to the second biasing mechanism a force against the biasing force generated by the second biasing mechanism in accordance with the rotational driving force.
