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 of it. Many of the universal covers you get won’t be a perfect fit but do work fine and can even tighten down too.
OEM Jet Ski Covers
The OEM PWC covers, the ones made by the same manufacturer as your watercraft, are going to fit the best. But this does not mean I consider them the best covers.
I’ve noticed that some people have trouble putting on the OEM covers compared to the universal fitting covers.
Another downside to the OEM covers is there cost. I will say they’re built really well and are thick. But a cover to me is something that will need to be replaced eventually, and I have an easier time buying more affordable universal fitting covers instead. I actually use a universal fitting cover for my Sea-Doo that I go into detail at the bottom.

What Jet Ski Cover Do I Use?
I personally own a Sea-Doo Spark, and the best jet ski cover I’ve found is this one here. (Amazon Link Ad) I stick with the universal fitting covers nowadays because the OEM ones are just too much to deal with.
This cover works great for me, keeps the sun off of it and the rainwater away from the footwells. I don’t have it on when I trailer the jet ski, but I don’t keep a cover on any jet ski I trailer. I’ve sold and bought many watercraft, and every time I’ve trailered a jet ski the cover would fly off so I don’t do that anymore.

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.
