ABSTRACT:
Two embodiments of protective cowlings for the power head of an outboard motor that form both forwardly and rearwardly facing air inlet openings so as to insure adequate air induction to the engine. The forwardly facing air inlet opening is located so as to avoid water being able to enter into the interior of the protective cowling and into the engine induction system.
