To improve electricity consumption of an electric motor.SOLUTION: An outboard engine 1 comprises: a driving source 3 composed of a first electric motor 31 and of a second electric motor 32; a propeller 4 with multiple blades 41 constituted so as to change a pitch and rotating around a center axis O5 of a propeller shaft 5 together with the propeller shaft 5; a propeller shaft rotation driving unit 6 which transmits driving force from the first electric motor 31 to the propeller shaft 5 and rotates the propeller shaft 5 around the center axis O5; and a pitch change driving unit 7 which transmits the driving force from the second electric motor 32 to each blade 41 to change the pitch of each blade 41. The propeller shaft rotation driving unit 6 has a first shaft 61 and the pitch change driving unit 7 has a second shaft 71 arranged closer to the bow side of a ship 10 than the first shaft 61.SELECTED DRAWING: Figure 3

    【課題】電動モータの電費を向上させることができる。【解決手段】船外機1は、第1電動モータ31および第2電動モータ32で構成された駆動源3と、ピッチ変更可能に構成された複数の羽根41を有し、プロペラシャフト5と共にプロペラシャフト5の中心軸O5回りに回転するプロペラ4と、第1電動モータ31からの駆動力をプロペラシャフト5に伝達して、プロペラシャフト5を中心軸O5回りに回転させるプロペラシャフト回転駆動部6と、第2電動モータ32からの駆動力を各羽根41に伝達して、各羽根41のピッチを変更させるピッチ変更駆動部7とを備える。プロペラシャフト回転駆動部6は、第1シャフト61を有し、ピッチ変更駆動部7は、第1シャフト61よりも船舶10の船首側に配置された第2シャフト71を有する。【選択図】図3
