PROBLEM TO BE SOLVED: To allow easy arrangement of an engine in a hull by reducing the size of an exhaust manifold. SOLUTION: A multiple cylinder engine 20 having an exhaust manifold 60 at the side is arranged with its crank shaft 21 along the longitudinal direction of a hull. The exhaust manifold contains exhaust pipes 61-64, to be connected to exhaust port 23a-23d of the engine, sorted at upper and lower sides to form combined pipes 62a, 64 at the upper and lower sides of the exhaust ports. The combined pipes are further combined to form an exhaust exit 67 ranging from the exhaust manifold. The exhaust exit is arranged at the approximate center in the height direction of an internal space of the hull, to which an exhaust turbo charger 70 is connected. |
