ABSTRACT:
A personal watercraft including a body including a hull and a deck covering the hull from above, an engine accommodated in an interior of the body, and an exhaust system that is accommodated in the interior of the body. The exhaust system includes an upstream muffler and a downstream muffler located on an upstream side and on a downstream side in a flow of the exhaust gas, the exhaust gas emitted from the engine flowing through the upstream and downstream mufflers, a first exhaust pipe through which the upstream and downstream mufflers communicate with each other, and a second exhaust pipe configured to extend from the downstream muffler outside the body. The upstream muffler and the downstream muffler are arranged in parallel, and the second exhaust pipe extends from the downstream muffler through a region that is located closer to the engine than the first exhaust pipe.
