    摘要: A water jet propulsion watercraft includes an exhaust passage, a catalyst member, a water lock, a first oxygen sensor, and a second oxygen sensor. The exhaust passage guides exhaust gas from an engine to an exterior of a hull of the watercraft. The catalyst member is arranged inside the exhaust passage. The water lock is arranged in the exhaust passage downstream of the catalyst member. The first oxygen sensor is arranged in the exhaust passage upstream of the catalyst member. The second oxygen sensor is arranged in the exhaust passage at a position downstream of the catalyst member and upstream of the water lock.

    摘要: A water jet propulsion watercraft includes a first exhaust pipe that is fixed to an engine and connected to an exhaust port of the engine. A damper section reduces vibrations from the engine. A catalytic converter unit is connected to the first exhaust pipe. The catalytic converter unit is attached to the engine through the damper section. A second exhaust pipe includes a first flexible pipe having a flexible quality and is connected to the catalytic converter unit. A water lock is fixed to a hull of the watercraft and connected to the second exhaust pipe.
