What Is the Fastest Jet Ski in the World?
The fastest production jet ski is the Kawasaki Ultra 310X, which reaches a top speed of about 67 mph (108 km/h). It is powered by a supercharged 1,498cc four-stroke engine designed for high-performance recreational riding.
In official tests and manufacturer data, the Ultra 310X consistently ranks as the quickest stand-up-style personal watercraft available to consumers. Its hull design and supercharged powertrain are optimized for rapid acceleration and high top-end speed.
Other high-performance models, such as the Sea-Doo GTX Wake Pro and Yamaha EX Sport, offer strong performance but fall short of the Ultra 310X's top speed. These alternatives focus more on touring, wake riding, or entry-level sport use rather than outright velocity.
