Yamaha SuperJet

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.[1] 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 1500 four stroke 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. The SX-R 800 was discontinued primarily due to the fact Kawasaki did not want to go through the hassle of trying to get around EPA regulations by marketing it as "closed course competition use only", instead opting to move on.

There are four engine generations spanning 1990-1993, 1994-1995, 1996-2020, and 2021-present, and four hull generations spanning 1990-1995, 1996-2007, 2008-2020, and 2021-present. 2019 marks the 30th year of production for the SuperJet.

The current model SuperJet is powered by a 1049cc inline three-cylinder, four-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.

The Yamaha FX-1 is the only other stand-up personal watercraft produced by Yamaha, and was produced in limited numbers from 1994 to 1995.

SuperJet 2008-2020 (SJ700BG-BV)[Generation 2-Upgraded Hull]

The last two-stroke powered 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.

length	88.2 in (SJ700AU)

width	26.8 in

height	26.0 in

dry weight	291 lb (SJ700AU), 375 lb (SJ1050W)

fuel capacity	4.8 U.S.gal, including 1.45 U.S.gal reserve. (SJ700AU),5.0 U.S.gal, including 1.45 U.S.gal reserve. (SJ1050W)

oil capacity	N/A, 50:1 fuel to oil pre-mix ratio TC-W3 oil, 3.10 U.S.gal (SJ1050W)

fuel consumption	7.7 gal/h max (SJ700AU), 8.0 gal/h max (SJ1050W)

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 starting in 2011 will usually require a license from IJSBA as they are classified as a "competition use only" watercraft, partly due to stringent EPA regulations for two-stroke engines. An annual membership from IJSBA is $65 for the first year as of May 2018, with renewal at $60 per year, if desired. These memberships can be purchased from the dealer in most cases. 2011 model year Superjet's also began to come with "Closed course competition use only" stickers on both the hood and exhaust.

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, which moves the rider forward slightly in the tray.

Mechanical Updates

The intake grate, pump, and ride plate are all set back 50 mm rearward compared to the past year SuperJets.

The engine remains as the same reliable two-cylinder twin carb as the previous 1996+ years, with no noted mechanical changes.

The impeller was updated to a newly designed geometry and made from stainless steel for the first time, 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 pump cavitation. The prop driveshaft was changed to a constant diameter over the entire length to increase stiffness, 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 to replace the original aluminum impeller design.
