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 Covers
The OEM 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 Do I Use?
What kind of Jet Ski website would this be if I didn’t have a Jet Ski nor a cover for it? Could you trust a website if that was the case?
I personally own a Sea-Doo Spark, and the cover I use for it is this one here. 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 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.
