The first commercially successful jet ski was developed and manufactured by Kawasaki. The original model, introduced in 1973, was named the “Kawasaki Jet Ski 400.” This marked the beginning of Kawasaki’s pioneering role in popularizing personal watercraft (PWC) globally. The term “Jet Ski” has since become synonymous with personal watercraft, although it is a registered trademark of Kawasaki. Other manufacturers, such as Bombardier (now BRP) with their Sea-Doo line, also contributed to the evolution and diversification of the PWC market in subsequent years.
