ABSTRACT:
A small watercraft powered by twin jet propulsion units, each driven by a respective engine. The engine is concealed within a hatch cover that has a larger portion which is removable for removal of the engine and a smaller portion which is pivotal for servicing of the engine without removing the larger portion. A centrally positioned operator's seat has a seat back with a handle so as to facilitate mounting of a rear deck and facilitate a passenger standing on the rear deck during operation. There are disclosed a pair of driving engines positioned within a V-hull in a central location so as to improve stability and yet permit extreme maneuverability. A fuel tank supplies fuel to the engines and is separated from the engines by a bulkhead with both the fuel tank and the engines being accessible when the smaller hatch cover is opened. A waterlock is also provided in the tunnel between the jet propulsion units for receiving and discharging the exhaust gases from the engine while precluding water from entering the engines through their exhaust systems in the event the watercraft becomes inverted.
