Patent ID: 7806741

Claim:
A marine propulsion device, comprising: a cowl defining a cavity; an engine having a plurality of cylinders, said engine being disposed at least partially within said cavity; an air intake manifold connected in fluid communication with said plurality of cylinders; a first inlet opening formed through said cowl; a first outlet opening formed through said cowl, said first inlet and first outlet openings defining a first flow path which directs a first stream of air from a position external to said cowl and proximate said first inlet opening to a region external to said cowl and proximate said first outlet opening, said first stream of air being directed to flow in thermal communication with said engine and transfer heat from within said cavity to said region external to said cowl and proximate said first outlet opening; and a second inlet opening formed through said cowl and connected in fluid communication with said air intake manifold, said second inlet opening and said air intake manifold defining a second flow path which directs a second stream of air from a location external to said cowl and proximate said second inlet opening to said air intake manifold, wherein said first and second streams of air are mutually exclusive with no air flowing within both of said first and second streams of air.
