The Best Jet Ski Covers For Your Exact PWC Size

The 2 worst things for your jet ski are the sun and water. Ironic isn’t it, but it’s true! This is why having a good 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 Makes For A good Cover?

When buying a PWC cover, there are a few things to keep in mind so you know you’re getting the right one.

  1. It should be tight, and if you can, made for your exact model of watercraft. So tight, that it seems hard to put on when new.
  2. The inside of it should have soft materials at the nose to protect the hood from rubbing. If not, use microfiber rags.
  3. You want to see vents if you intend to use it for towing.
  4. Some have quick access to the gas cap or storage, that is a huge plus and something to keep an eye on.
  5. Look for ones that point out where the nose and handlebars are, this makes putting it on easier. If not, use a silver sharpie to mark the spots on the outside to make your life easier in the future.

What Size Do You Need?

What size jet ski cover you need will vary from 88 inches up to 140 inches long.

The average 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 one that is too big than one that is not big enough. Your main goal is to keep the sun off vessel. 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 Option

The best cover you can buy will be the manufacturer’s OEM.

A manufacturer’s OEM cover is made exactly to fit your watercraft and will be the best option if you trailer your craft. You will not find a better fitting material unless you get one custom-made.

When buying a OEM, it’s important you pay attention to the year and model of your vessel. They usually sell them 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 Option

The next best to get will be a universal fitting ones as listed in the next sections.

The universal fitting 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 one. OEM covers tend to be more expensive, and having the universal on protects it during the off-season and keeps it going for longer.

What Do I Use?

I go with OEM, but I also throw a universal one on top of it during winter storage.

The OEM 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 They Worth It?

A cover is worth it, especially if you keep it where the sun gets to it.

The sun will fade the plastic and fiberglass of your jet ski. The sun will also tear up your seats and creates cracks in them.

Instead of your hull and body taking the damage, the cover will, and covers are much cheaper than replacing the parts the sun destroys.

How Long Do PWC Covers Last?

They will last 3 to 5 years, depending on how much sun and abuse it takes.

It’s better for the covers to take the damage than your fiberglass, and thus why we use them. The sun is harsh on plastic and fiberglass, so it’s best you get a covers and replace it when it wears out, or else your watercraft will take the damage.

Stop Rodents From Eating Your Machine!

Rodents like to eat plastic and rubber, so keeping your watercraft covered is important. They can crawl in under the seats, make a nest, have a family, and eat the rubber. You would think the rubber and plastic would kill them, but it doesn’t. Rodents also attract snakes, so you can see how this problem needs to be solved.

You want to keep the exhaust port and hoses protected. This is why I use two covers, the OEM and a large universal one to go over the rear of the craft.

This is more of an issue if you keep your watercraft out near woods or on the water, muskrats are a real problem. I’ve also noticed that if you have a dog or cat that hangs around your ski, that most rodents avoid it. I’ve tried rat poison but don’t have much luck with it, but I find simply spraying down your machine jet pump and engine compartment with silicone lubricant spray helps, they don’t seem to like the taste of silicone. You need to let the machine air out for a few minutes as those sprays are flammable! This also protects the parts from rust, and a good measure to do anyways, especially if you ride in saltwater.

  1. 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.

  2. 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?

  3. 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.
