ABSTRACT:
A cowling for an outboard motor of the type having a water propulsion device powered by an internal combustion engine positioned within an engine compartment defined by the cowling, is disclosed. The cowling has at least one intake vent positioned therein and includes an engine cover which defines an isolated intake air path from the vent across a top end of the engine to an engine air intake. The cover also defines a chamber in which a flywheel rotated by the crankshaft at the top end of the engine is positioned. The chamber has an inlet in communication with the engine compartment, and an outlet leading to an exhaust passage. The exhaust passage leads to an exhaust vent in the cowling.
