To enhance maintainability of a water pump assembly.SOLUTION: An outboard motor 100 includes: a lower portion 120 including a propeller shaft 134; and an upper portion 110 including an engine 131. A support portion includes a movable case member 17 and a steering shaft member 5. The support portion rotatably supports the lower portion 120 relative to the upper portion 110 about a steering shaft 5a and rotates integrally with the lower portion 120. The upper portion 120 is provided with a water pump assembly 10. When viewed along an axis direction (direction parallel to an axis P2) of the steering shaft member 5, the water pump assembly 10 overlaps the lower portion 120 at a first rotation position (straight advance position) of the lower portion 120 with respect to the upper portion 110. Meanwhile, at least a portion of the water pump assembly 10 does not overlap the lower portion 120 at a steering position (second rotation position) at a time of rightward or leftward maximum steering.SELECTED DRAWING: Figure 2

    【課題】水ポンプアセンブリのメンテナンス性を高める。【解決手段】船外機100は、プロペラシャフト134を含むロワー部120と、エンジン131を含むアッパ部110とを備える。支持部は可動ケース部材17および転舵軸部材5を含む。支持部は、転舵軸5aを中心にアッパ部110に対してロワー部120を相対的に回動可能に支持し、且つ、ロワー部120と一体に回動する。アッパ部120には水ポンプアセンブリ10が設けられる。転舵軸部材5の軸心方向(軸心P2に平行な方向)からみて、アッパ部110に対するロワー部120の第1の回動位置(直進位置)では、水ポンプアセンブリ10はロワー部120と重なる。一方、左または右への最大転舵時の転舵位置(第2の回動位置)では、水ポンプアセンブリ10の少なくとも一部がロワー部120と重ならない。【選択図】図2
