Kawasaki Jet Ski Top Speed Specs

How fast can a Jet Ski go? Depending on the model, Kawasaki Jet Ski top speed numbers vary from 54 – 67 mph.

The slowest Jet Ski is the Ultra LX Jet Ski with a top speed of 54 mph. This model arrives with the same hull as the performance models, while it produces only 160 HP.

Thanks to its good fuel range and reliability, the Ultra LX is popular among average buyers and considered the best fishing Jet Ski as well.

If you want something more nimble and playful, you should look at the new 2021 Kawasaki STX 160 series. These models are the upgraded version of the STX-15F, which offered the same 160 HP engine and can reach 62 mph.

However, there aren’t real tests for the new STX 160 series available, regarding the fact that these models arrive with the same engine and in the same weight range as the STX-15F, we can expect around the same top speed on these Jet Ski models.

It’s the same issue with the SX-R Stand Up Jet Ski’s top speed, powered with the same engine it can reach around 62 mph again.

Top speeds of the performance Jet Skis are definitely the highest in the Kawasaki’s fleet, they hit 67 mph in stock condition. You can choose from four different models:

How fast does a Kawasaki STX-15f go?

The Kawasaki STX-15f can go as fast as 62 mph, as this jet ski is powered with a 160 HP, 4-stroke, 4 cylinder, non-supercharged engine.

How fast does a Kawasaki STX-160 go?

Just like the STX-15f, the top speed of the Kawasaki STX-160, 160x, and lx is 62 mph. Because the STX-160 series arrives with the same engine, pump, and hull, as the STX-15f, you can find differences only in the top decks and features.

How fast is the Kawasaki Ultra LX?

Although this model belongs to the Ultra family, the Ultra LX is also powered with the 160 HP non-supercharged engine option. With this power source, the Kawasaki Ultra LX’s top speed is 62 mph.

How fast is the Kawasaki 310 jet ski?

Unlike its smaller brothers, the Kawasaki Ultra 310 series is manufactured with a supercharged, 310 HP engine. Thanks to this stronger power plant, the top speed of all Kawasaki 310 jet skis is limited to 67 mph.

How fast does a stand-up jet ski go?

The Kawasaki SX-R 1500 stand-up jet ski can go as fast as 62 mph. Unlike the competitor stand-up models, the SX-R 1500 is powered with a 160 HP 4-stroke engine, which makes the new SX-R the fastest stand-up jet ski on the market.

Yamaha WaveRunner Top Speed Specs

Would you like to know how fast can a WaveRunner go? When it comes to Yamaha WaveRunner’s top speed numbers, they don’t get left behind Kawasaki’s Jet Skis.

Even their entry-level models, the Yamaha EX series can go as fast as around 50 mph while the EXR offers 55 mph.

If you looking for a bigger WaveRunner, the VX series is for you. They can reach a top speed of around 53 mph.

Yamaha’s luxury WaveRunners, the FX series, arrive with supercharged and non-supercharged engines as well.

The non-supercharged Waverunners, like the FX HO or the FX Cruiser HO, can run even 63 mph, while the supercharged FX SVHO Line can run as fast as 67 mph.

You can expect the same top speed on the performance WaveRunners, namely, the GP1800R HO and GP 1800R SVHO.

Sea-Doo Top Speeds

Would you like to know how fast can a Sea-Doo go?

Sea-Doo top speed numbers vary widely, as they have the largest fleet from all manufacturers. It also means that you can choose from several good models if you consider buying one.

Their low-end model is the Spark 60 HP, which is currently the cheapest Sea-Doo on the market, and the GTI 90 (powered with the same engine) can run around 42 mph. 

The Spark 90HP and Spark TRIXX models can run around 48 mph while the GTI 130 series around 52 mph.

The BRP’s dedicated fishing watercraft, the 2021 Sea-Doo Fish Pro’s top speed is around 55 mph, while the performance Sea-Doo’s top speed can reach easily 67 mph.


How to reach the top speed on your PWC?

As you would have understood by now, the top three fastest Jet Skis, Waverunner, and Sea-Doo models have it in them to go much faster than 65 – 67 mph, although they can’t do so straight off the shelf.

PWC fans know it pretty well that if you wish to have a faster ride, the best thing for you to do is modify your craft so you can achieve more power. But everybody does not want to modify or bring changes in their craft.

Due to this, before you delve into the PWC modifications, here are some easy tricks you can adopt for getting higher top speed on your PWC.


Calm Weather conditions: When you want to increase the speed of your PWC, the preferred type of water is rough. Although it is not only choppy water that could decrease your speed, it does play a part. So, it is better that you first test out on smooth waters. It is not recommended that you test the PWC top speeds during high winds.

The best thing to do would be testing when there is no wind, as air conditions also act as a factor and could impact your ride’s speed. Your PWC would move quickly in low humidity instead of high. Air pressure and high humidity make the engine work harder, as a result, engines become slowed down. Another important factor is the temperature. Your energy’s power could be affected on a hot sunny day.


Less fuel: PWC tank sizes go from 6 gallons to even as high as 20 gallons. A full tank with 20 gallons, means around 130 lbs (60 kg) weight, which is a noticeable extra weight! If you want to reduce your curb weight and ride faster, attempt with less fuel. But be careful, and never drain your tank completely as you always need fuel to get back to the shore. Safety should always come first!


Modifications – Make your PWC faster

As far as the modification is concerned, there is a wide range of tunings kits and aftermarket parts you can choose from.

A common method of PWC modification is installing a special speed control override module, through which you can make your engine perform to its full capacity. You would have to install a different impeller with this unit too.

You can find these units at the famous watercraft performance specialist including RIVA Racing or PWC Muscle. You could reach up to 75 mph on the basis of this modification only. Do you want to make your watercraft more faster?

If you require more performance and speed from your PWC, there are many ways to do so.

You can install racing kits andaftermarket performance parts that could makeyour PWC’s top speed into the 80-90 mph range.

You should also know that only those manufacturers offer you the option of modification who are planning to enter some contest or competition.

It is not recommended that casual PWC users modify their PWC, it is possible and many are doing it. You just need to find a service shop that would assist you.

Last but not least, know that your watercraft’s warranty might get affected if you go through with the modification. But it is not a definite thing. At the end, everything depends on the manufacturer and your dealership.


The top speed of the world’s fastest modified watercraft

Depending on the above information, you might wonder about the fastest modified PWC present in the world – that also has made it to the world record.

The top speed ever to be achieved on a watercraft was by Uva Perez, who made a record by riding a modified Yamaha Waverunner at a whopping 127 mph.

The fastest and the most powerful of WaveRunner models are famed because of their capacity for modification and to achieve amazing speeds. Perez’s modified Yamaha was no exception.


Conclusion

As you must have known by now that Sea-Doo, WaveRunner and Jet Ski top speed numbers vary at large, depending on the model.

We have also described how PWC speeds depend on many factors including the climate and even your weight.

If you wish to boost your PWCs power or want to participate in a racing competition, you could modify your machine. But always remember to take the necessary safety measures and ride safely. Do not forget to follow the rules when you are out on the water.
