Abstract
An improved air inlet cover for use with outboard motors is disclosed. A particular embodiment of the cover is formed by a generally hollow shell having an open side. An air passage is located opposite the open side at an upper portion of the shell. A baffle extends from an upper inner portion of the shell to an elevation below the air passage and is disposed generally opposite the air passage. An exit port is provided at the bottom of the chamber for discharging water collected therein, and a valve is provided within the exit port. When the exit port is submerged the valve is closed and provides a barrier to water entry. Preferably, the cover is located at an upper forward portion of the outboard motor cowl and both the air passage and air inlet are high up on the upper forward portion.
