What Is The Speed Of A Jet Ski? 

Do you know the speed of a jet ski? If you don’t know, then read this article till the end. Because here we are going to give you the speed of a jet ski and how to calculate it by using a formula. Perhaps, many people do not know about jet skis. Well, a jet ski is the trademarks name of a personal watercraft or PWC produced by the Kawasaki Motor Company, but the term has become a generic name for all types of personal watercraft. It is a part water skiing device and part speedboat, with a definite hint of the motorcycle during operation. Let’s come to our main topic which is the speed of a jet ski

What Is The Speed Of A Jet Ski? 

The speed of a jet ski is between 40 miles per hour and 70 miles per hour, which is depending upon how calm the water is, the amount of wind resistance, and the weight of the passengers. The fastest speed of a jet ski is 67 miles per hour and the average speed of a jet ski is 57 miles per hour. But many riders never go beyond 40 miles per hour as they learn the ropes. Doing 40 miles per hour on a jet ski feels like doing 80 miles per hour in your car and shocked many new riders. 

What is the max speed of a jet ski? So, the maximum speed of a jet ski is 67 miles per hour in the United States, as their engines are electronically limited. Overriding the speed of the limiter you can expect around 75 miles per hour on the fastest jet ski. But with additional modifications, you can reach up to 90 miles per hour.  For those interested in jet skiing, it may be helpful to find and scan QR code free resources for tips and tricks on how to modify and enhance the performance of your jet ski.  

 Now, you know the top speed of a jet sky. What is the average speed of a jet ski? So, the average speed of a jet ski is around 57 miles per hour. The Max speed f a jet ski can be measured in other units as, 

  • A Jet ski top speed km/h is between 65 km/h and 99 km/h  
  • Jet ski top speed knots are between 40 and 70 mph.   

Now you have an idea about the speed of a jet ski, let’s know how to calculate it. 

Calculate The Speed Of A Jet Ski 

The calculation of the speed of a jet ski is very simple. First of all, you need to measure some variables, and then by using a formula you can calculate the speed of a jet. Here is the formula to calculate the jet ski’ speed, 

Vr = V(Fo-F)/(Fo+F) Vr 


Fo – is the upstream frequency  

F – is the downstream frequency 

Vr – is the velocity of a Jet Ski 

V – is the velocity of sound in air 

Let’s consider an example in order to execute this formula, 

A physicist out at the cabin uses a sonar device to determine the speed of a jet ski on the nearby pond. A 25.5 kHz signal is sent out and a 27.5 kHz signal is returned. Assume the speed of sound in air is 340 m/s. What will be the speed of a jet ski? 

By using a formula, 

Vr = V(Fo-F)/(Fo+F) Vr 

The speed of a jet ski = 340 x (27.5 – 25.5)/(27.5 + 25.5) Vr 

                                   = 12.83 m/s or 46.2 km/h. 

About A Jet Ski 

A jet Ski is a small machine like a motorcycle that is powered by a jet engine and can travel on the surface of the water. The jet ski went from a novelty personal watercraft early on in its lifecycle to a beach fad, a phenomenon, to be the standard for all personal watercraft, and finally, a seminal part of the pro racing circuit. Like a motorcycle speeding through the water, it is one of the pieces of equipment that many athletes and weekend warriors simply cannot live without. 

In other words, a jet ski is a water sport similar to powerboat racing, in which riders use jet skis to compete. The sport is mostly practiced at the recreational level in several countries around the world.

Why Are Jet Skis Limited To 67 Mph?

To address this problem and to protect the general boating population, the Coast Guard and personal watercraft manufacturers created a ‘gentlemen’s agreement’ in 1999 to limit the top speeds of Jet Skis to 65 mph. Though the agreement is informal, manufacturers choose to comply to improve the safety of their products.

How Fast Does A 230 Hp Jet Ski Go?

Although the GTR 230 is the entry-level model in the Performance family, there is no shame when it comes to its skills! Like any other supercharged jet ski, the top speed of the Sea-Doo GTR 230 is a restricted 65 mph, but under ideal conditions and with a small rider it can reach 67 mph!

Although the GTI SE 170 is the flagship model in the Recreation family, it still comes with a naturally-aspirated engine rated at 170 HP. Despite this, there is no shame in its performance! Based on our research, the Sea-Doo GTI SE 170 accelerates from 0 to 50 mph in 5.0-5.5 seconds, and it tops out at 53-55 mph.


In this article, you come across the speed of a jet ski and also learn how to calculate it in detail. The Jet Ski is a trademark of Kawasaki, and the jet ski is the general name we all use for this type of watercraft. Like dirt bikes, the jet ski models also all have a lot in common, looking very similar in their overall design. But there is one that stands out, and that’s the standing jet ski. Now, you have an idea about the speed of a jet ski.
