Abstract
An exhaust gate valve apparatus of a water jet propulsion-driven watercraft is provided that is capable of positively closing an exhaust port with a valve body when an engine is stationary and widely opening the valve body when the engine runs. In the watercraft, an exhaust port of a tail pipe is arranged to face an opening in a top wall of a pump chamber. The exhaust gate valve apparatus includes a valve body, valve body support flange, pressure device, and a jet water expelling device. The valve body support flange attaches the valve body to the top wall. The pressure device urges the valve body to a closed position. The jet water expelling device diverts jet water from a water jet pump and opens the valve body using the jet water thus diverted, counteracting a pressing force of the pressure device and opening the valve body.
