1999 Yamaha WaveBlaster 800 Specs and Review [Video]

The third-generation WaveBlaster 800 was more powerful and significantly heavier than its predecessors, namely the WaveBlaster 700 and the WaveBlaster 760.

1999 Yamaha WaveBlaster 800 Review

Yamaha revealed the race-intended, first-generation WaveBlaster 700 in 1993. This tiny nimble ski offered a motorcycle-like riding experience and became extremely popular among sport-minded riders.

This machine was a mix of a sit-down and a stand-up PWC since it was closely related to the SuperJet.

Although the Blaster 1 was a really popular machine, riding it required some practice, athletic skills, and a good sense of balance. Therefore, this ski was not for everyone.

To make this model more attractive to the average rider, Yamaha released the upgraded WaveBlaster 760 for the 1996 model year. This ski had a significantly bigger hull that measured 107.1 inches in length and 40.6 inches in width.

For the best performance, this ski was powered by a 754cc, 2-stroke, twin engine rated at 90 HP.

This second-generation WaveBlaster was manufactured from 1996 through 1999.

In the same year that the Blaster II resigned, Yamaha introduced the upgraded, third-generation WaveBlaster 800.

The official model name of this ski was WaveBlaster WB800, but it was also known by many different names such as WaveBlaster III, Blaster 3, “Euro Blaster,” or just simply WB3.

The hull and top deck of the new Blaster 800 were completely redesigned from scratch, and it measured 107.1 inches in length, 40.9 inches in width, and 38.0 inches in height.

Although this platform was almost the same size as the Blaster II, it offered a different riding experience. It was an authentic race hull that featured a unique top deck with an unusually long nose.

Unfortunately, its engine made the ski quite heavy as the dry weight of the WaveBlaster 800 was 496 pounds. In contrast, the dry weight of the Blaster II was 397 pounds, while the tiny Blaster 1 weighed only 320 pounds!

Therefore, many racers found the Blaster 3 too heavy for racing. But the model found its market and became popular among recreational riders.

The WB800 was considered a great recreational ski for playing around, but it wasn’t recommended for freestyle or surfing.

Thanks to its bigger hull, it offered more stability than its siblings. It was also equipped with a rear grab handle, which made deep-water reboarding much easier. (Surprisingly, the Blaster 1 lacked this simple feature!)

The key advantage of the Blaster 800 was arguably its high-performance engine. As the name suggests, the machine was powered by a 784cc 2-stroke twin featuring two Mikuni BM44 carburetors and a reed-valve intake system (a.k.a. YPVS power valve) CDI ignition, oil injection, and open-loop cooling system.

This lively power source cranked out an amazing 120 HP at 7,000 RPM. The fuel consumption of the Blaster 800 was 12.9 GPH, so it drained its fuel tank in about 50 minutes at full throttle.

The engine delivered its power to an axial-flow, single-stage jet pump that enclosed a 3-blade, stainless-steel impeller.This 144mm jet pump proved to be too small for this powerful engine, so it was prone to cavitate.

Another drawback of the WaveBlaster 3 was that its power valves required periodic inspections and upgrades.

Standard features included factory-installed sponsons, tow hook, rear grab handle, shut-off switch, 1.06-gallon oil tank, and a 10.6-gallon fuel tank with a 2.27-gallon reserve. The Blaster 3 also offered some storage space, which was split into a bow storage and an under-seat storage bin.

Apart from the above, the ski was very minimalist as it was designed without any gauges, trim, reboarding step, or other convenient features.

To the greatest regret of many WaveBlaster fans, the WB 800 was never marketed in the U.S. due to environmental restrictions.

The model had been part of Yamaha’s PWC fleet for only two short years before being discontinued in 2000.
