To facilitate attachment of a lower housing to an upper housing in an outboard engine.SOLUTION: A shaft includes a second spline and extends upward from a lower housing. The second spline engages with an engine cowl or a first spline inside an upper housing. The second spline includes a tip unit and a body unit. The tip unit is provided on a top end of the shaft. The body unit is provided below the tip unit. A groove width in the periphery direction in the tip unit is greater than a groove width in the periphery direction in the body unit in the second spline.SELECTED DRAWING: Figure 4

    【課題】本発明は、船外機において、ロアハウジングのアッパハウジングへの取り付けを容易にすることを目的とする。【解決手段】シャフトは、第2のスプラインを含み、ロアハウジングから上方に延びる。第2のスプラインは、エンジンカウル又はアッパハウジング内の第1のスプラインと噛み合う。第2のスプラインは、先端部と本体部とを含む。先端部は、シャフトの上端に設けられる。本体部は、先端部の下方に設けられる。第2のスプラインにおいて、先端部における周方向の溝幅は、本体部における周方向の溝幅よりも大きい。【選択図】図4
