To provide an outboard engine having a novel structure especially in a configuration related to a supercharger, and a vessel comprising the outboard engine.SOLUTION: An outboard engine 4 comprises an engine 19, a supercharger 41, an intercooler 42, a bypass passage 52, and an air bypass valve 53 that opens and closes the bypass passage 52. The engine 19 comprises a cylinder block 24, and an intake passage 43 and an exhaust passage 36 connected to the cylinder block 24. The supercharger 41 is interposed in the intake passage 43, and the intercooler 42 is interposed in the intake passage 43 between the cylinder block 24 and the supercharger 41. In the bypass passage 52, one end 52A is connected to a region 43B upstream of the supercharger 41 in the intake passage 43, and the other end 52B is connected to a region 43C downstream of the supercharger 41 in the intake passage 43. The air bypass valve 53 is directly attached to the intercooler 42.SELECTED DRAWING: Figure 3

    【課題】とりわけ過給器に関連する構成において新規な構造を有する船外機、及び、この船外機を含む船舶を提供する。【解決手段】船外機4は、エンジン19と、過給器41と、インタークーラ42と、バイパス通路52と、バイパス通路52を開閉するエアバイパスバルブ53とを含む。エンジン19は、シリンダブロック24と、シリンダブロック24に接続された吸気路43及び排気路36とを含む。過給器41は、吸気路43に介装され、インタークーラ42は、吸気路43においてシリンダブロック24と過給器41との間に介装されている。バイパス通路52では、吸気路43において過給器41よりも上流の領域43Bに一端52Aが接続され、吸気路43において過給器41よりも下流の領域43Cに他端52Bが接続されている。エアバイパスバルブ53は、インタークーラ42に直付けされている。【選択図】図3
