ABSTRACT:
An outboard motor includes an engine having an air intake device. The cowling has an engine room in which the engine is disposed. One or more air intake openings are formed through the cowling. A water separation device is included in the cowling interposed between the air intake opening and the engine room. A first intake passage of the water separator communicates with the ambient air opening. A second intake passage communicates with an upper portion of the first intake passage. If a large flow of water enters the first intake passage through the air opening, such water flows out of the cowling through another opening and/or into a holding chamber formed in the cowling so as not to flow into the second intake passage.
