ABSTRACT:
A ventilating system for an outboard motor having a water propulsion device and an internal combustion engine positioned in a cowling, the engine having an output shaft arranged to drive the water propulsion device, is disclosed. The ventilating system includes an air inlet in the cowling which permits air to flow into an engine compartment in which the engine is positioned, and an exhaust port positioned in the cowling. The system also includes a mechanism for drawing air through the inlet into the compartment and expelling air out of the compartment through the exhaust port after the engine has stopped.
