An exhaust manifold of reduced size simplifies installation of an engine in a boat body. A multiple cylinder engine 20 having an exhaust manifold 60 on a side portion thereof is disposed such that a crankshaft 21 thereof extends along forward and rearward directions of a boat body. The exhaust manifold has a structure wherein exhaust pipes 61 to 64 connected to exhaust ports 23a to 23d of the engine are distributed upwardly and downwardly in such a manner as to form confluence pipes 62a and 64 above and below the exhaust ports and the confluence pipes are further joined to each other to form an exhaust gas exit 67 from the exhaust manifold. The exhaust gas exit is disposed at a substantially central portion of an internal space of the boat body in the vertical direction and an exhaust gas turbo charger 70 is connected to the exhaust gas exit.
