PROBLEM TO BE SOLVED: To provide an outboard motor capable of lowering the intake air temperature of an engine and cooling auxiliary machines of the engine.SOLUTION: An outboard motor comprises: a moisture-intake air separation space in an upper part of an engine cover; auxiliary machines of an engine 14, which are provided inside the engine cover; a flywheel magnet device having a flywheel provided at an upper end portion of a crankshaft of the engine 14, which penetrates an engine block 35, and a magnet provided below the flywheel; and an exhaust opening formed in the engine cover. By rotation of the flywheel of the flywheel magnet device, air after being removed of moisture in the moisture-intake air separation space in the upper part of the engine cover is sucked in from an air suction opening 43 in the upper part of the engine 14 and an air flow is formed, which cools the auxiliary machines of the engine 14 and then is discharged from the exhaust opening.

    【課題】エンジンの吸気温度を下げると共に、エンジンの補機類を冷却することのできる船外機を提供する。【解決手段】船外機は、エンジンカバー上部の気水吸気分離空間と、エンジンカバー内に設けられるエンジン14の補機類と、エンジンブロック35を貫通するエンジン14のクランクシャフトの上端部に設けられるフライホイールと該フライホイールの下方に設けられるマグネトとを有するフライホイールマグネト装置と、前記エンジンカバーに形成される排気口と、を備え、前記フライホイールマグネト装置のフライホイールの回転により、エンジンカバー上部の気水吸気分離空間にて水分を除去された空気をエンジン14上部の空気吸入口43より吸引し、エンジン14の補機類を冷却した後に排気口から排出される気流が形成されることを特徴とする。【選択図】図2
