ABSTRACT:
An outboard motor S includes an internal combustion engine E having a crankshaft7, and an alternator G having a shaft81and a housing82. The engine E and the generator G are disposed in an engine compartment15with the crankshaft7of the engine E and the shaft81of the alternator G spaced a center distance d apart from each other. The housing82is provided with air inlets83through which cooling air for cooling the interior of the alternator G flows into the housing82and air outlets84through which cooling air that has cooled the alternator G is discharged as exhaust air. An exhaust air duct91surrounds the outlets84of the housing82and carries the exhaust air to a predetermined position from which the exhaust air cannot easily flow again through the inlets83into the housing82. The alternator G spaced the center distance apart from the internal combustion engine E can be cooled at improved cooling efficiency.
