PROBLEM TO BE SOLVED: To provide a small watercraft that can use a sufficient supercharging effect. SOLUTION: An engine 20 with an exhaust manifold 60 is installed with its crankshaft along the longitudinal axis of a hull, and a turbocharger 70 driveable or rotatable by exhaust out from the exhaust manifold is installed just behind the exhaust manifold 60 and the engine. The turbocharger is arranged, with its shaft interconnecting the turbine and compressor along the lateral axis of the hull, the turbine on the exhaust manifold side, and the compressor on an engine intake port side. An intercooler 50 is arranged in juxtaposition to the compressor and below an intake chamber.
