The 2 worst things for your jet ski is the sun and water. Ironic isn’t it, but it’s true! This is why having a good jet ski cover is so important.
What size do you need? Will it hold up? Is it even worth it? All those questions and more I answer below.
What Size Jet Ski Cover Do You Need?
What size jet ski cover you need will vary from 88 inches up to 140 inches long.
The average jet ski cover length to get is 133 inches long, but going with a longer 140 inch cover will work too if you’re not sure what size to get.

Still not sure on what size to get? It’s better to get a cover that is too big than one that is not big enough. Your main goal for when it comes to a jet ski cover is to keep the sun off it. Many of the universal covers you get won’t be a perfect fit but do work fine and can even tighten down too.
The Best Jet Ski Cover
The best jet ski cover you can buy will be the manufacturer OEM cover.
A manufacturer OEM cover is made exactly to fit your jet ski and will be the best option if you trailer your jet ski with the cover on. You will not find a better fitting cover unless you get one custom-made.
When buying an OEM cover, it’s important you pay attention to the year and model of your jet ski. They usually sell the covers in groups, like the GTS, GTI, GTI SE, GTI Limited (2011-2019) is one group as they all share the same body. If you’re not sure what year model you have, the last two digits of your VIN will tell you the year. So if the last two digits of your VIN are “19” then you have a 2019 model.

The Next Best Jet Ski Cover
The next best jet ski cover to get will be a universal fitting ones as listed in the next sections.
The universal fitting jet ski covers fit most jet skis, but they will be more bulky and less fitting.
One thing I like to do, especially during winter storage, is put a universal fitting cover on top of my OEM cover. OEM covers tend to be more expensive, and having the universal cover on protects it during the off-season and keeps it going for longer.

What Jet Ski Cover Do I Use?
I use the OEM cover, but I also throw a universal fitting cover on top of it during winter storage.
The OEM cover has vents at the front to create a vacuum when towing your jet ski, so it stays tight on it. These vents also allow water in, so that is why I like having the second universal fitting cover over it during long-term storage.
Are Jet Ski Covers Worth It?
A jet ski cover is worth it, especially if you keep it where the sun gets to it.
The sun will fade the plastics and fiberglass of your jet ski. The sun will also tear up your seats and creates cracks in them.
Instead of your jet ski taking the damage, the cover will, and covers are much cheaper than replacing the parts the sun destroys.
How Long Do Jet Ski Covers Last?
A jet ski cover will last 3 to 5 years, depending on how much sun and abuse it takes.
It’s better for the cover to take the damage than your jet ski, and thus why we use them. The sun is harsh on plastic and fiberglass, so it’s best you get a cover for your jet ski and replace it when it wears out, or else your jet ski will take the damage.

Thanks again for the informative website. Would you alter any of your suggested after-market covers given the 2021 models? This is purely anecdotal (based on one review posted to Amazon) but it was suggested that 2021 Yamaha VX models are wider than they used to be suggesting some of these covers might not fit. Does this sound accurate to you? Do you think that as long as I got the large cover option from any of the possible providers listed above that I’d be okay for my 2021 Yamaha VX Cruiser HO? Thanks!
A large universal cover should fit a VX body, it’s not that much bigger than the last body. The FX might have an issue though. The best fit will always be one from the manufacturer. The most common thing I see when it comes to covers is that people put them on wrong and think it’s too small. The trick is handlebars first, then the nose, and the rear last.
Thanks Steve!
Just put a deposit on the 2021 Seadoo Fish Pro. Its pretty darn long (147″)and with the addition of the LINQ cooler would just going with a Sea Doo branded cover suffice?
For sure go with the stock Sea-Doo cover. The Fish Pro has an awkward size that many of the 3rd party covers won’t fit.
Thanks for the INFO my son is looking wanted a bigger SEA DOO GT 230 the looked at the SPARK 3 UP. HOW DO YOU LIKE YOURS? What would you tally son the difference #1 is price But do you like the Spark better for him I think he would not so much receding a BIGGER. He has a SEA RAY he wants something to get on when he dent want to get the big boat out
I love my 3up Sea-Doo Spark. Compared to a GTR 230 it’s more playful and way better on gas. But the GTR 230 is going to be faster and more comfortable of a ride. Comparing the two it depends on what you want, do you want playful or speed? If this is his first jet skis maybe give the Spark a try for a season, but if he wants to upgrade to something faster and more comfortable then go with the GTR. My only suggestion if you go with the Spark is to get the models with iBR for better control around the dock. One extra bit, if his Sea Ray is big enough he could easily get attachments for it so he can dock a Spark on the back of it.
