1994-1995 Yamaha FX-1 Review

Yamaha FX-1 Review

Contrary to popular belief, the SuperJet is not the only stand-up jet ski Yamaha made.

Just like the second-generation Yamaha SuperJet, the lesser-known FX-1 also made its debut in 1994. These machines replaced the outdated first-generation “square nose” SuperJet.

Are you wondering what justified the existence of the FX-1? The short answer was the gaining popularity of the stand-up segment.

In the early ‘90s, stand-up jet skis were extremely popular. In the middle of the decade, no less than four jet ski manufacturers produced stand-ups; with some of them offering more models.

One of the most famous stand-up fleets belonged to Kawasaki, which consisted of three different models, the Kawasaki 550SX, 650SX, and the 750SX.

Yamaha tried to gain a larger share of the market by releasing two different stand-up skis. Obviously, the FX-1 was released to compete with the widely popular Kawasaki 550SX, while the SuperJet was close to the 650SX.

Simply put, the FX-1 combined the slim hull design of the Kawasaki 550SX with the power of the 701cc SuperJet.

The latter was a larger model that was intended for closed-course racing. Therefore, it was built on a larger platform and housed a more advanced, 144mm jet pump.

In contrast, the Yamaha FX-1 had a lighter and more nimble “freestyle” hull designed for slalom racing. Thanks to its narrower hull, it required much less space for turning.

Although the FX-1 shared its 701cc, 62 HP, 2-stroke twin engine with the SuperJet, its outdated 122mm jet pump restricted its performance.

Regarding dimensions, the ski was 83.9 inches long, 42.8 inches wide, and 26.8 inches high. The dry weight of the FX-1 was only 267 pounds, which was about 24 pounds less than the SuperJet.

It also has a smaller, 3.7-gallon fuel tank, which offered only around half an hour of play if you were hard on the throttle. This was not a surprise, as the max. fuel consumption of the Yamaha FX-1 was 6.9 GPH at full throttle.

Performance?

According to the original owner’s manual, the top speed of the Yamaha FX-1 was about 47 mph under ideal conditions.

Because of its lively attitude, the FX-1 was harder to ride than bigger stand-up skis, but it also offered a lot of fun for experienced riders.

What’s more, the ski also came with some advanced features like CDI ignition, a different flywheel design, and a factory-installed bilge pump.

What Happened to the Yamaha FX-1?

Surprisingly, although the FX-1 was introduced in 1994, it was discontinued after the 1995 model year. Eventually, only around 1500 were made of this unique Yamaha stand-up.

But why did it disappear from the market so quickly?

First, the FX-1 inherited its jet pump from the retired WaweRunner 500 family. This outdated 122mm pump provided less thrust, which severely limited the performance of the ski.

Even if it utilized the powerful 62 HP engine option, its performance lagged behind the SuperJet and other competitor models. Its nimble hull was also hard to ride on rough waters.

The model was also not competitive because its hand-made fiberglass hull made its production costs too high. The FX-1 cost more than the more powerful high-end Kawasaki 750SX.

As you might assume, the FX-1 didn’t sell well, and Yamaha decided to stop making them after only two short years of production.

Many riders waited for this model to return with some improvements, but unfortunately, it never did.

Yet, you can still see many of them running on the water! However, these machines are often actually an FX-1 hull upgraded with a more powerful engine, a larger pump, and other aftermarket performance modifications.
