Kawasaki Jet Ski 300 Personal Watercraft (1986-1988)

The Kawasaki Jet Ski 300 series, including the JS300 and 300SX models, defined personal watercraft performance from 1986 to 1988. These stand-up jet skis were powered by a robust 2-stroke, single-cylinder 294cc engine, consistently delivering 30 horsepower across all variants. A significant evolution occurred in 1987 with the introduction of the 300SX. While sharing the same 294cc, 30 HP engine, the 300SX featured a more advanced platform. It boasted a smaller, more modern hull (78.74 inches long, 26.4 inches wide) compared to the JS300's larger design (84 inches long, 24.4 inches wide), making it more agile but less stable. Engine configuration also differed, with the 300SX using a reed valve and a Mikuni BN38 carburetor, distinct from the JS300's piston reed valve and Mikuni BN34. The 300SX was positioned as the successor, leading to the discontinuation of the JS300 after 1988. Q: How do I know which parts fit my specific Jet Ski 300?
