Abstract

A boat includes an outboard motor having an internal combustion engine enclosed within a cowling. The cowling has a rear inlet port for allowing outside air to be drawn into the cowling. A closure member selectively closes the inlet port depending upon a certain engine operating parameters. In another embodiment, the cowling also includes a front air inlet port, and a front closure device for selectively opening and closing the front inlet port.
