Watercraft top speed has got to be the most common question I get asked.
The top speed can vary from 40 to 70 mph, depending on the model.
The fastest a stock model can go is 70 mph due to a gentleman’s agreement with the US coast guard. However, ones delivered outside the United States don’t always have this 70 mph limit and can often go slightly faster.
The average speed is 57 mph, but many new riders never go beyond 40 mph as they learn the ropes. Doing 40 mph feels like doing 80 mph in your car and shocks many new riders.
Modified racing machines can reach speeds over 100+ mph.
The fastest modified PWC goes a little over 140 MPH:

Fastest Production Jet Skis
All manufacturers have their top of the line, fastest models, from the factory as listed below.
- Sea-Doo RXP-X 325
- Yamaha GP SVHO
- Kawasaki ULTRA 310X
These models are the “racing” models and are the fastest in not only top speed, but also take-off speed.
The hulls on the Sea-Doo RXP-X 325 and Yamaha GP SVHO are smaller and tuned for racing. In the US, all 3 watercraft are capped at 70 MPH, but outside the US they don’t have the top-speed-limiter and can go beyond 70 MPH.
These are racing watercraft, but other models feature the same engines. For instance, the Sea-Doo RXP-X 325’s larger counterpart is the RXT-X 325, which has the same engine but a larger body. The bigger body enables it to better handle choppy waters and perform more efficiently in straight-line racing.
If you want the fastest straight line watercraft, then it will be the Sea-Doo RXT-X 325 followed by the Kawasaki ULTRA 310X.
How To Go Faster!
There are several ways you can make your jet ski faster, from easy to hard, let’s cover them!
Easy Speed Increases
- Use the correct key or driving modes.
- Remove extra weight.
- Make sure the wear ring and impeller are not damaged.
- Make sure the supercharger is working if you have one.
- Run premium, non-ethanol gas.
- Get race sponsons.
- Speed control bypass, some models computers won’t let you go over a certain speed, so you need a module that bypasses the GPS signal.
- ECU Tuning. May require you to ship the ECU out or go somewhere to get it reprogrammed.
Hard Speed Increases
- RIVA kits.
- Buy a faster model, some will only go so fast.
- Replace intake grate.
- Get a new impeller.
- Cold air-intake.
- Performance exhaust system.
If you have a supercharged jet ski, especially one that uses GPS for speed like a Sea-Doo, then getting the speed control bypass will be the easiest and fastest way to increase your top speed.
Keep in mind, some of these modifications will void your warranty.
Most models today have speed limiters that allow you to restrict the top speed.
For example, Sea-Doo has an ECO mode that limits top speed to 45 mph.
A lot of models even have a learning mode or learning key that can be programmed from 32 mph to 50 mph. The jet skis that can’t be programmed are stuck at 35 mph.
You also have more modes, like touring that makes the jet ski slower to take off but still gets to top speed. This is nice if you want to cruise and not launch out of the water.
These modes are not new; for example, Sea-Doo has Touring and Sport mode since 2009 and became more available after 2011.
