ABSTRACT:
A number of embodiments of four-cycle internal combustion engines having belt-driven overhead cam shafts. The power head of the outboard motor includes a protective cowling that has an atmospheric air inlet and the air drawn through this atmospheric air inlet is directed over a timing belt that drives the cam shaft from the engine crankshaft for its cooling. The air flow is controlled either by utilization of fans, baffles and/or utilizing the flow of air caused by the induction system.
