How to Tune a Jet Ski?

Buying a jet ski is already an amazing idea, but at the same time you want to have a great experience and enjoy the moment. Many times, you will want to focus on tuning that unit and taking it to the next level with some extremely high speeds. But in order to do that, you most likely have to tune it. And that brings the question, how do you tune a jet ski?

There are many things to keep in mind about jet skis, they can be tuned but it will take a bit of trial and error to do so properly. This is why you need to think about the tools required to complete the tune-up process and what you can actually tune in the first place.

Maintenance is Key

If you’re looking to start tuning your jet ski, the best thing that you can do is to try and keep the jet ski engine at the top of its level. What that means is you have to change the old parts that are not fully functional and replace them with new ones. That severely affects the overall performance of the unit. Then there’s also the fact that you want to deal with dust or dirt accumulations. These will appear due to daily use, so removing them will help your jet ski function a whole lot better.

Buy Third Party Jet Ski Mods

There are modded parts on the market designed from the ground up to make your pwc go a bit faster. What you will like about them is the fact that they can be an engine that’s faster, a better impeller or anything similar to that.
Improve the exhaust kit
The rule of thumb when it comes to jet ski tuning is that you end up paying $1000 or so for every extra 1mph. So it’s quite expensive to get a lot of extra power from the jet ski. But an upgrade like a better exhaust kit does help you a lot. In this case, you want to go with one that has a narrow channel cone. That means you can get a better speed since the jet ski is able to channel a much larger water volume thanks to the narrow opening. This leads to more thrust, and you will be faster on water. However, don’t believe that this changes the horsepower of your unit, because it won’t do such a thing. But it will give a bit of extra juice, which sometimes it’s all you really need.

Jet Ski Intake Grate Upgrades

For a lot of people the intake grate upgrade is the best one to help you improve your jet ski speed. Some say that no intake grate is actually going to make a lot of sense, because the top speed is faster due to having less obstructions. That might be true, especially if you are in rough waters. But then again, jams will appear from time to time, so you really have to figure out what you are getting into here and what you can deal with.
Alternatively, you can choose to have the intake grate upgraded. Those persons that perform such a jet ski tune up state the additional weight is worth it. The intake grate will direct water to the intake and you will have more power when you turn. Granted, even if you want to have a high speed when you go straight, the intake grate will help you stabilize yourself on the water. Replacing the intake great with a newer one isn’t always that expensive.

Regardless of what option you choose when it comes to the intake upgrade, dealing with this might help you quite a bit. It gives you an amazing experience, and you will certainly appreciate the great results and really good value and quality.

PWC Weight Upgrades

As a rule of thumb, when you want something to go faster, you need to remove some of the extra weight. Obviously that translates really well in the case of a jet ski too. In fact, a regular jet ski tends to have a lot of stuff that you don’t need if you just want to have a very high speed on the water. Things like coolers, extra gas, anchors, ropes and additional gear or compartments will affect your top speed, and that can obviously be a problem.
What you want to do is to create a list with the items that you really need on the water. If there are items that you just don’t need at all, remove them from your jet ski. As you can imagine, this will increase the overall top speed quite a bit. Ideally you just want to have a few gallons in your tank and you should go without any unnecessary supplies. Remove the extra weight and as you do that, you will get more mph. The number of mph you get will depend on what you remove.

Jet Ski Impellers

Not a lot of people know this, but the type of impeller you use and its angle will end up affecting your jet ski speed. Since there are so many models on the market, it’s very hard to figure out which one works for you. What you can rely on is a set of reviews from industry experts and even customer reviews that state their own experience.

That being said, the impeller replacement won’t always give you a huge performance change. Still, there are aftermarket impellers that can give you a very high speed. They have the potential to boost the top speed of your jet ski. Even if you’re getting an extra 2-3mph, if you add that up with the other chances made here, it can actually come in handy and help you more than you might imagine.

Should you go to a third party shop to help you tune the jet ski?

While you can do this manually, if you lack any experience and you want to be safe, working with a team of experts might be the way to go. They will know what pieces to replace and which are the best replacements. In a situation like this everything matters and you will be able to obtain a very good speed. So yes, if you don’t really know how to handle this type of tuneup, working with experts will help you. Do keep in mind that every shop might charge you differently, so that’s something to keep in mind. Normally you should go to a jet ski maintenance shop if you want to upgrade your jet ski engine. Replacing an engine is not always a great idea since it’s expensive, but if you go with a custom built engine you can obtain a very good tune up experience.


We encourage you to really take your time and see what changes suit your needs and which ones are not going to be that great. It all comes down to finding the right approach and fully understanding the process in a meaningful manner. It’s a great idea to know what you are getting into and what you can expect in a situation like this.

Make sure that you read some reviews and all kinds of different guidelines to see what changes worked for other people. Ideally you want to find modded parts created for your particular jet ski model. And you should always make sure that you work only with reliable professionals, just to be safe, the more you focus on results and on a great experience, the better it will be. Just try to use that to your advantage and you will appreciate the outcome.
