Jet Ski is the brand name of a personal watercraft (PWC) [1] manufactured by Kawasaki, [2] a Japanese company. [3] The term is often used generically to refer to any type of personal watercraft used mainly for recreation, and it is also used as a verb to describe the use of any type of PWC.

A runabout-style PWC typically carries one to three people seated in a configuration like a typical bicycle or motorcycle.

Kawasaki Jet Ski

"Jet Ski" is a proper noun and registered trademark of Kawasaki. Released in 1972, the stand-up Kawasaki Jet Ski was the first commercially successful personal watercraft in America (after reaching a license agreement with the inventor of the Sea-Doo, Clayton Jacobson II when his license agreement with Bombardier expired). [2] The Kawasaki Jet Ski was the only commercially successful PWC for almost 16 years, from the introduction of the WSAA in October 1972 through the reintroduction of the sit-down, runabout-style Bombardier Sea-Doo in 1988. [4] [5]

With the introduction of the Jet Ski, Kawasaki helped create the United States Jet Ski Boating Association (USJSBA), in cooperation with aftermarket companies and enthusiasts. In 1982 the name was changed to the International Jet Sports Boating Association (IJSBA). At the start, only JS440 stand-ups were raced. After Kawasaki introduced the runabout-style X2 in 1986, it gained its own class, later to be renamed the "Sport Class". [4]

Stand-up model history

1972–1976

Kawasaki introduced the first production stand-up PWC in October 1972. [6] The WSAA and follow-on WSAB were powered by modified 400cc 2-stroke twin-cylinder engines. The WSAA was designed with a flat hull and the WSAB came with a convex v-hull design. The design concept distinctive of these original craft included a fully enclosed impeller for safety, self-righting, and self-circling features. Without a lanyard the self-circling allowed the rider to swim back to the idling craft after falling off. Kawasaki called them "Water Jet" and "Power Skis" before they settled on the name "Jet Ski". [7]

1976–1982

The 1976 JS400 was popular among thrill-seeking recreational riders and racers. The 1977 JS440 offered more power and performance. It was one of Kawasaki's longest-selling models. In 1982, Kawasaki introduced the JS550, which had better performance. The 550 featured a newly designed high-capacity mixed-flow pump, driven by a 531cc engine. The 550 introduced an automatic rev limiter to prevent engine damage when the pump cavitates. The JS550 also introduced underwater exhaust for quieter operation.

1982–1986

While the JS550 continued to be improved, in 1986, Kawasaki introduced the JS300. The JS300 was a single-cylinder 294cc two-stroke engine featuring automatic oil injection. They also added the 650 X2, their first sit-down Jet Ski, and originator of the Sport Class for PWC racing.

1987–1992

Kawasaki introduced the JS650SX. It featured a higher capacity axial flow pump and a powerful 635cc two-stroke twin engine in a modified V-hull design for increased maneuverability and stability.

In 1992, the company introduced a stand-up JS750-A. The engine was a twin-cylinder 743 cc two-stroke with reed valves and automatic oil injection. The redesigned hull was lighter in weight and more maneuverable.

1995

The 750 SXI (JS750-B) was introduced and became the first stand-up Jet Ski with dual carburetors.

2003

Kawasaki introduced the SX-R 800 (JS800A), which increased displacement to 781cc, in the form of an in-line twin 2-stroke engine, generating 80hp. The SX-R also moved to a fiberglass-reinforced plastic (FRP) hull and top deck.

2011

Due to US EPA restrictions, Kawasaki released their final two-stroke stand-up, and discontinued the JS800 SX-R. The model was designated the JS800ABF. [8]

2017

On October 6, 2016, Kawasaki reintroduced the stand-up Jet Ski. The SX-R 1500 shared little with its predecessors. It was 8 feet 9 inches (2.67 m), 550+ pounds (250 kg), powered by a 160 horsepower (120 kW) inline 4-cylinder four-stroke engine. [9]

Jet ski

Kawasaki produced various models of the Jet Ski starting in 1972, beginning with the JS400 and leading up to the current JS1500.

Other stand-up manufacturers

In 1990 Yamaha introduced the Super Jet. It was designed in consultation with Clayton Jacobson II. 2020 marked the last model year offered with a 2-stroke as the 2021 model featured a 4-stroke engine.

In 1994–1995 Yamaha introduced the FX-1, which had a limited production of 1500 units.

In 2002-2004 Polaris made the Octane, 777cc 2 stroke 2 Cylinder

The number of personal watercraft-related accidents has increased with the popularity of personal watercraft (PWC) since their introduction during the late 1960s. The use of the term jet ski for all types of PWCs is a misnomer; Jet Ski is a registered trademark in the United States for a line of PWCs manufactured by Kawasaki. With the increased use of personal watercraft since their inception, the hazards accompanying their use have also increased. According to U.S. government reports, most accidents are associated with rental operators, underage operators, under-trained and undereducated boaters and a variety of factors associated with recreational-boating accidents. Due to their affordability, ease of use, and relatively low transportation and maintenance costs, personal watercraft have significantly increased the number of water-based enthusiasts in the U.S. This rise in participation has created conflicts between the various boating segments in the U.S. and a need for additional boater education. Recreational-boating accidents are the second-largest transportation-related cause of injury in the U.S..
