The SuperJet is a stand-up type personal watercraft (PWC) made by Yamaha Motor Corporation. Part of Yamaha's WaveRunner line of watercraft, it was introduced in 1990 and has become one of the most successful stand-up personal watercraft ever made. All SuperJets, including the engine, are hand-built in Japan. Credit for the design is given to Clayton Jacobson II.

Prior to the introduction of the new Kawasaki SX-R on October 6, 2016, it has been the only stand-up sold by a major manufacturer since the Kawasaki SX-R 800 was discontinued in 2011.
There are three engine generations spanning 1990-1993, 1994-1995, and 1996-2017, and three hull generations spanning 1990-1995, 1996-2007, and 2008-2017.
The current model SuperJet is powered by a 701cc inline two-cylinder, two-stroke engine.
All generations have an upper and lower hull constructed from SMC (sheet molded compound). SMC is a compression moldable composite material made of long strands of glass fibers suspended in a polyester resin.

SuperJet 1994-1995 (SJ700S-T)[Generation 1-Upgraded Engine)
The body remains the same as the previous generation with a "Square nose" top deck and standard SuperJet bottom deck.

Chassis
SuperJet 1996-2007 (SJ700AU-BF)[Generation 2]
The body consists of a new "Round nose" top deck (or hull) and the same standard SuperJet bottom deck as the previous "Square nose" model.

SuperJet 2008-2017 (SJ700BG-BR)[Generation 2-Upgraded Hull]
The current SuperJet (produced by Yamaha Motor and hand-built in Japan) has been visually the same since 1996. The 2008 model was the first year of a new bottom deck, changed for the first time in the history of the SuperJet.
This watercraft no longer meets California or New York two-stroke emissions standards as a new vessel (however, previously titled vessels can still be registered in CA).
Purchasing a SuperJet new from a dealer will usually require a license from IJSBA as they are classified as a "competition use only" watercraft due to stringent EPA regulations for two-stroke PWCs. An annual membership from IJSBA is $45 per year as of September 2016.
Body Updates
The new 2008 has the same Roundnose top deck that was introduced in 1996, with a new bottom deck (or hull) incorporating the first changes since 1990 when the SuperJet was released.
The new bottom hull has incorporated side sponsons (similar to adding "Blowsion tubbies") onto the hull. The rear of the hull is also slightly narrower and has deeper strakes for improved tracking.
The handle pole on the 2008 SuperJet is 50 mm shorter than previous generation Roundnose SuperJets.
Mechanical Updates
The intake grate, pump, and ride plate are all set back 50 mm rearward compared to the past SuperJets.
The engine remains the same as the previous 1996+ years with no noted mechanical changes.
The impeller was updated to a new stainless steel design, in comparison to the previous aluminum design that remained the same throughout 1990-2007. The new impeller design offers large improvements in hookup as well as reduced cavitation. The driveshaft was changed to be a constant diameter over the entire length, versus previous years in which it is necked down to a smaller diameter in the center section. However, the impeller is backwards compatible with all older models and can be installed on any year SuperJet from the original aluminum impeller design.
