Abstract
An outboard motor S includes an internal combustion engine E having a crankshaft 7, and an alternator G having a shaft 81 and a housing 82. The engine E and the generator G are disposed in an engine compartment 15 with the crankshaft 7 of the engine E and the shaft 81 of the alternator G spaced a center distance d apart from each other. The housing 82 is provided with air inlets 83 through which cooling air for cooling the interior of the alternator G flows into the housing 82 and air outlets 84 through which cooling air that has cooled the alternator G is discharged as exhaust air. An exhaust air duct 91 surrounds the outlets 84 of the housing 82 and carries the exhaust air to a predetermined position from which the exhaust air cannot easily flow again through the inlets 83 into the housing 82. The alternator G spaced the center distance apart from the internal combustion engine E can be cooled at improved cooling efficiency.
