ABSTRACT:
A protective cowling arrangement provides atmospheric air to the engine of an outboard motor for engine cooling and combustion while inhibiting water intake. The protective cowling incorporates one or more air inlets, an air chamber, and ducts of different sizes for permitting atmospheric air to enter the engine compartment. One of these ducts, which is disposed in part above electrical components of the engine, is substantially shorter in length than the other duct. This duct thus has a smaller flow area without unduly restricting air flow through the duct. An air chamber cover is affixed to the engine and shields the ducts to afford further water preclusion.
