Abstract
An outboard motor comprises a cowling, having a top cowling and a bottom cowling, that cooperate to define an engine compartment. An intake air duct draws outside air into the engine compartment. A water collecting part is arranged in the bottom cowling for accumulating water that may enter the cowling through the air duct. A water passage may also be provided for guiding water from the intake air duct to the water collecting part. The water passage may have air openings for allowing air to enter the engine compartment independent of the water. A floor of the engine compartment may be adapted to contain water splashing and direct water to a water collecting part.
