Abstract
A marine propulsion device is provided with an air control system that draws air from the region under the cowl of the outboard motor and induces a flow of air out of the region. The air is caused to flow through a second opening formed in the cowl. As a result, air drawn into the cowl through a first opening can flow either into the engine through its throttle body mechanism or out of the space under the cowl, as induced by the operation of the fan.
