The SuperJet is a personal watercraft (PWC) made by Yamaha Motor Corporation. The SuperJet is a "stand-up" PWC. Credit for its design is given to Clayton Jacobson II. Part of Yamaha's WaveRunner line of watercraft, it was introduced in 1990 and has become one of the most popular stand-up personal watercraft in history.
The SuperJet is powered by an Inline 2-Cylinder, 2-Stroke engine.
There are three engine generations spanning 1990-1993, 1994-1995, and 1996-2016, and three hull generations spanning 1990-1995, 1996-2007, and 2008-2016.
All models have an upper and lower hull constructed from SMC (sheet molded compound) fiberglass.

SuperJet 2008-2016 (SJ700BG-BR)[Generation 2-Upgraded Hull]
The current SuperJet (still in production by Yamaha Motor and built in Japan) has been visually the same since 1996. The 2008 model was the first year of a new bottom deck, previously unchanged 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).
Body Updates
The new 2008 has the same Roundnose top deck that was introduced in 1996, with a new bottom deck 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 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 previous 1996+ years with no mechanical changes.
The impeller was updated to a stainless steel impeller from the previous aluminum impeller that remained the same from 1990-2007. The new stainless impeller offers large improvements in hookup as well as reduced cavitation. The driveshaft was changed to be constant diameter over the entire length, versus previous years in which it is necked down in the center section. However, the impeller does remain backwards compatible with all older models.
