1973: created the JET SKI® watercraft... and it was good.

Launching a revolution, the world's first JET SKI watercraft took to the water. These limited production models were powered by 2-stroke twin-cylinder engines pumping out plenty of thrust for waterborne fun. Featuring greater manoeuvrability than any boat and extremely shallow drafts, they set the standards for the personal watercraft of the future. The unique JET SKI watercraft feature of the fully enclosed impeller pump dramatically improved water safety over conventional outboard motors. Self-righting and self-circling features ensured that the craft would idle in circles at slow speeds if the rider fell off. The WSAA and WSAB could be distinguished by their hulls: the WSAA featured a flat hull, while the WSAB featured a V-type hull.
1976 Mod. JS400
Kawasaki's first mass production JET SKI watercraft, the JS400, rolled down the slipways and into the hearts of the world's fun seekers. Featuring an SMC hull, the JS400 was a popular machine among racers and thrill seekers alike.
1977 Mod. JS440
