Jet Ski Top Speed – How Fast Are Jet Skis?

Jet ski top speed has got to be the most common question I get asked. To answer this question I’ve created a chart and addressed the other common questions relating to speed.

The fastest jet skis from the factory max out at 70MPH (113KPH).

The slowest jet ski from the factory is the 60HP Sea-Doo Spark, and it goes 40MPH (64KPH).

The average jet ski speed is 57MPH (93KPH).

The top speed numbers come from personal experience and research.

Can You Make Your Jet Ski Faster?

Yes, there are upgrades that allow your jet ski to go faster than stock.

These upgrades vary; some are as simple as reprogramming your jet ski and some require significant work to the engine and exhaust.

To learn more, check out Riva Racing.

Can You Make Your Jet Ski Slower?

Yes, most of the models you get today have limiters on them.

For example, Sea-Doo has an ECO mode that limits top speed to 45MPH.

A lot of models even have a learning mode or learning key that can be programmed from 32mph to 50mph. The ones that can’t be programmed are stuck at 35MPH.

You also have more modes like Touring mode 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.

That Doesn’t Sound Fast?

I do get a few people tell me 40MPH or 55MPH doesn’t sound fast.

While 40MPH in your car may not seem fast, on a jet ski, it feels like 80MPH.

I’ve had a few customers new to the sport who won’t go past 35MPH because it’s too fast for them. I remember my first time on a jet ski and being blown away by the pure take-off power.

You don’t have a roll cage around you like in a car, so you hear all the wind noises, and you sit a lot closer to the water, so it feels like you’re going faster than you are.

Don’t let the lower speeds confuse you; all jet skis you get today are fast. Jet ski manufacturers don’t fight over top speed, they fight over 0 to 30MPH and 0 to 50MPH numbers. Every jet ski you buy today feels like it jumps out of the water when you go full throttle! This is especially true for new riders.

I’m Sure My Jet Ski Does 100MPH!?

I’ve had customers tell me there jet ski does over 100MPH stock.

There has never been a production model jet ski that has done over 70MPH from the factory.

What they’re confusing is MPH with KPH or KM/h.

100KPH = about 60MPH

And 60MPH is a standard top speed for many models. 57MPH is the average in the chart at the top.

Yamaha VS Sea-Doo VS Kawasaki

Of the leading 3 manufacturers, who makes the fastest jet ski?

Well, all 3 are capped at 70MPH due to a gentleman’s agreement with the coastguard.

Sea-Doo and Kawasaki are the only ones with 300HP engines, but the racers love to use Yamaha.

Sea-Doo has the tech, Kawasaki has the bigger engine, and Yamaha has the hull.

Things are getting more interesting since Sea-Doo updated the RXP-X, and Yamaha has made some fine-tunes to the already great GP1800R SVHO. At the end of the day, it’s going to come down to personal preference. The manufacturers lay the groundwork, it’s the racers that do the impressive stuff.
