Description of the Related Art In an outboard motor, an engine in which a crankshaft is generally arranged vertically and ancillary engine accessories and the like are covered with an engine cover, and the engine cover constitutes an appearance of the outboard motor. Meanwhile, an alternating current generator (ACG: hereinafter referred to as a generator) is disposed in the engine, and the generator is driven by a belt / pulley mechanism or the like by a crankshaft. The generator is one of the heat sources, and one of the causes of the heat generated by the generator is that the ambient temperature in the engine cover (in the engine room) of the outboard motor rises, thereby increasing the intake air temperature. As a result, the engine performance may be degraded, and therefore, it is preferable to cool the generator.

型の船外機の外形のコンパクト化が図れる。According to the first aspect, the outside air intake and the water separation passage provided in the engine cover can be manufactured by screwing the front cover and the air guide to the engine cover. Therefore, the structure of the engine cover is extremely simple, and the front cover and the air guide are screwed to the engine cover, so that the structure can be made simple, easy, and inexpensive. Also, screw the front cover with a slit for taking in outside air in front of the opening of the engine cover, etc., inside the engine cover,
Since the passage member also serving as the air guide is screwed to the position including the opening, the air guide also serves as the water separation passage, so that the number of parts is reduced, and since no dedicated water separation passage member is provided, the inside of the engine cover is not provided. Therefore, no oily space is required, so that the outer shape of a large outboard motor equipped with a large-sized, high-output engine can be reduced in size.

ことができる。The outside air rises from the slit of the front plate through the opening of the engine cover through the inner groove-shaped first passage, separates the moisture, and a part of the rising cooling air from which the moisture is separated is ACG. Of the cooling air which is supplied from the upper part of the generator to the periphery of the generator through the space between the standing piece and the upper inside of the front part of the engine cover without involving the exhaust air of From the upper end of the second passage, it passes through the inside, flows downward, is discharged from the lower end, rises and cools the generator, so it supplies cooling air with water separated from the top and bottom of the generator to generate electricity that dislikes moisture. The machine can be reliably and effectively cooled.
