摘要: A vehicle, including watercraft and personal watercraft, includes a hull, an engine system and a propulsion system. The engine system comprises an internal combustion engine and an air intake for receiving air to be mixed with fuel supplied to the engine. The propulsion system connects to the engine and propels the watercraft along a surface of a body of water using power from the engine. The watercraft can include a quick connect air/water separator, or air box. A fuel system is provided that has a fuel supply line and a fuel return line which are connected with a bypass line. For evacuating fuel from the supply line and the return line, the bypass line contains a valve which can be actuated to allow fuel to flow into the fuel reservoir. A lubrication system is provided that includes a filler neck comprising an oil/air separator which allows a mixture of oil and air to be separated and the oil to be returned to the oil reservoir.

摘要: The present invention provides a jet pump assembly that includes a rotatable shaft adapted to be operationally coupled to a power source. An impeller is operationally connected to the rotatable shaft. A housing surrounds at least a portion of the rotatable shaft operationally coupled to the impeller. In addition, a single bearing is disposed between the housing and the rotatable shaft, permitting rotation of the rotatable shaft therein. The bearing has at least an inner race operationally coupled to the rotatable shaft and an outer race operationally coupled to the housing. The bearing also includes at least two sets of rolling components disposed, side-by-side between the inner and outer races, permitting rotation of the inner and outer races with respect to one another.
