To provide a ship propulsion machine capable of collecting fine dust such as microplastics contained in water from the sea, lakes, rivers, etc.SOLUTION: An outboard engine as a ship propulsion machine comprises an internal combustion engine, a propeller 3 to convert the power of the internal combustion engine to a ship propulsion, a power transmission mechanism (a drive shaft 4, a gear unit, and a propeller shaft 6) to transmit the power of the internal combustion engine to the propeller 3, a casing (a shaft casing 8, a gear casing 9, etc.) to cover the internal combustion engine and the power transmission mechanism, and a fine dust trap device 21. The fine dust trap device 21 is provided in the gear casing 9, and comprises a water intake 22 to take in water around the outboard engine, a trap device 25 to trap the fine dust contained in the water taken from the water intake 22, and an exhaust port 35 to drain water after trapping the fine dust by the trap device 25.SELECTED DRAWING: Figure 3

    【課題】船舶推進機により、海、湖、河川等の水に含まれるマイクロプラスチック等の微小塵を回収できるようにする。【解決手段】船舶推進機としての船外機は、内燃機関と、内燃機関の動力を船舶の推進力に変換するプロペラ3と、内燃機関の動力をプロペラ3に伝達する動力伝達機構(ドライブシャフト4、ギヤ装置、プロペラシャフト6)と、内燃機関および動力伝達機構を覆うケーシング(シャフトケーシング8、ギヤケーシング9等)と、微小塵捕捉装置21とを備えている。微小塵捕捉装置21は、ギヤケーシング9に設けられ、船外機の周囲の水を取り込む取水口22と、取水口22から取り込まれた水の中に含まれる微小塵を捕捉する捕捉器25と、捕捉器25により微小塵の捕捉を行った後の水を排出する排水口35とを備えている。【選択図】図3
