Abstract
An air intake system for an outboard motor provides parallel air flow paths between an opening formed in a cowl of the outboard motor and an air intake manifold of an engine under the cowl. A first air path flows in a relatively direct path between the opening in the cowl and the first inlet of a plenum chamber. A second air flow flows in a less direct path from the opening in the cowl to a second inlet of the plenum chamber. The second air flow is used to remove heat from a preselected component, such as an alternator, before it rejoins the first air flow within the cavity of the plenum chamber and is directed, in combination with the first air flow, through an intake air conduit connected to an outlet of the plenum chamber and to an air intake manifold of the engine.
