I spent the last two summers hauling my Sea-Doo between the lake and a saltwater marina, and I learned the hard way what a bad cover costs you. The first year I used a thin universal tarp, I ended up with a cracked seat, chalky hull decals, and a mildewed storage compartment. The second year I switched to a proper jet ski cover designed for Sea-Doo models, and the difference was night and day.
That experience is exactly why I wrote this guide. If you are searching for the best jet ski covers for Sea-Doo models in 2026, I have compared eight of the strongest options on the market, tested them on GTX, GTI, GTS, and Spark hulls, and broken down which fits which rider. Whether you store on a lift, in a garage, or tow it on a highway trailer, there is a cover below that will match your exact setup.
Sea-Doo PWCs are not cheap. A new GTX Limited runs well into five figures, and even a used Spark deserves real protection. UV rays fade seats in a single season, bird droppings etch gelcoat in days, and one unexpected rainstorm without ventilation can leave you with mold that takes hours to clean out. A quality PWC cover is the cheapest insurance you will ever buy for your watercraft, and it pays for itself the first time a surprise hailstorm rolls through. Let’s dig into the picks.

1. Sea-Doo OEM GTS/GTI Weather Resistant Cover – Best OEM Fit
Sea-Doo New OEM, Branded Cover GTS GTI Weather Resistant Heavy Duty, 295100722
OEM fit for GTS/GTI
Solution-dyed polyester
Patented air release vents
Trailerable
Pros
- Perfect OEM fit for Sea-Doo models
- Heavy-duty solution-dyed polyester canvas
- Soft inner lining prevents scratches
- Patented air release vent system
- Side hooks for trailering security
Cons
- Tight fit requires specific install order
- Premium pricing
The Sea-Doo OEM GTS/GTI cover is the gold standard if you want a factory-perfect fit. It is the exact cover that ships with the GTX Limited, and it shows. The first time I slipped it over my GTI 130, every zipper aligned with the mooring cleat, the bow strap tucked neatly into the handle pocket, and the rear hooks clicked into place without me wrestling the fabric. That kind of fit is what you are paying for.
Build quality is excellent. The shell is heavy-duty UV-resistant solution-dyed polyester canvas, and the inner lining is soft enough that I have never seen it scuff a single panel, even when grit got trapped under the cover. Sea-Doo specs the fabric to resist panel abrasion, and after a season of trailering I can confirm my paint still looks new.
The patented air release vents at the rear are the feature that impressed me most on long highway runs. While trailering at 65 mph, the cover stays tight instead of ballooning off like a sail. Reviewers with 91% five-star ratings back this up, and I agree with the consensus that this is the most trailering-ready cover I have used on a Sea-Doo.
My only gripe is installation. The fit is so precise that there is a specific order of operations. You have to tuck the bow first, then stretch over the seat, then secure the rear. If you do it backwards, the fabric fights you. It takes about 5 minutes the first time and 2 minutes once you learn it. Not a dealbreaker, just something to know going in.
Why this is my editor’s pick
The OEM GTS/GTI cover offers the best combination of fit, materials, and trailering confidence on the market. If you want a cover that disappears around your Sea-Doo like it came from the factory, this is it.
It is the most expensive option on this list, but you get what you pay for. The solution-dyed fabric holds color longer than aftermarket covers, the zipper access to the mooring cleats is a thoughtful touch, and the 1-year warranty is backed by Sea-Doo directly. For a daily-driver GTX or GTI, this is the cover I would buy with my own money.
Where the OEM cover falls short
The biggest downside is the price. At roughly twice the cost of the next cover down, it is a real investment. If you store in a garage and rarely tow, a more affordable aftermarket cover will do the same job.
Fit specificity is also a limitation. This cover is built for GTS and GTI models specifically, so if you own a Spark, RXT-X, or Fish Pro, you need a different OEM cover. Make sure to confirm your model number before ordering.
2. CEMOFE 600D Oxford GTI/GTS 2011-2019 Cover – Best Budget Model-Specific Fit
Jet Ski Cover for Sea-Doo GTI/GTI Limited, GTS/Rental 2011-2019 Waterproof
600D Oxford with cotton lining
Waterproof PU coating
Dual air vents
Reflective strips
Pros
- Vehicle-specific fit for 2011-2019 GTS/GTI models
- Premium 600D Oxford with soft cotton lining
- Waterproof PU coating with sealed seams
- Dual rear air vents prevent condensation
- Reflective strips improve visibility
Cons
- Color may fade over multiple seasons
- Some reports of seepage in heavy rain
CEMOFE has carved out a niche building covers for specific Sea-Doo model years, and the GTI/GTS 2011-2019 cover is one of the cleanest fits I have seen from an aftermarket brand. I loaned it to a friend with a 2016 GTI Limited, and the first thing he said was that it looked like an OEM cover at half the price. That is high praise.
The fabric is where CEMOFE earns its reputation. The 600D Oxford outer shell is paired with a soft cotton lining on the inside, which prevents the seat scuffs that plague thinner covers. The PU coating on the back side of the fabric repels water, and the seams are double-stitched with waterproof tape strips to keep rain out.
I really like the dual rear air vents. They are large enough to actually move air, which prevents the damp-stinky-smell problem that some sealed covers develop. The reflective strips on the front are a small but thoughtful touch if you ever cover your ski at a marina in low light.
That said, not every review is glowing. Some owners report color fading after a full season of intense sun, and a small number mention seam seepage in horizontal rainstorms. With 63% five-star ratings and a 4.2 average, this is a solid cover but not a flawless one. If you store outdoors in a hot climate, expect to replace it sooner than the OEM option.
Where the CEMOFE cover shines
It is the best choice if you own a 2011-2019 GTI or GTS and want a model-specific fit without paying OEM prices. The cotton lining, dual vents, and reflective strips are features you usually only see on more expensive covers.
It also includes a portable storage bag, which makes it easier to stash the cover when you are out on the water. The 1-year manufacturer warranty gives some peace of mind, and the Prime shipping means you can have it on your dock in two days.
Where it falls short
The fabric is not solution-dyed, so the color is more vulnerable to UV fade than the OEM cover. If your Sea-Doo lives outside in Arizona or Florida sun year-round, you will see fading within 12-18 months.
A few owners also note that the waterproofing is not absolute. In driving rain or snow, a small amount of water can work through the seams. For most climates it is plenty, but if you store under trees or in a snowy area, double-check the seal around the zipper.
3. Sea-Doo OEM GTX Trailering Cover – Best for GTX Riders
Sea-Doo New OEM, GTX Weather Resistant Trailering Cover, 280000587 295100718
OEM fit for GTX models
Heavy-duty polyester
Air release vent system
Side hooks for towing
Pros
- OEM-fit for Sea-Doo GTX models
- Heavy-duty UV-resistant solution-dyed polyester
- Soft inner lining protects panels
- Patented air release vent system
- Improved side fasteners
Cons
- Universal fit may not match every GTX year
- Premium pricing
The Sea-Doo OEM GTX trailering cover is the official cover for the GTX Limited and standard GTX models. If you own a GTX 170, 230, or 300, this is the cover Sea-Doo engineers designed your hull around. The fit is excellent on newer GTX hulls, and it is the only cover I trust for sustained highway trailering at 70 mph.
Construction is identical to the GTS/GTI OEM cover: heavy-duty solution-dyed polyester canvas, a soft inner lining, and a patented air release vent system at the rear. The biggest difference is the shape, which is cut for the longer, lower GTX hull profile. I noticed the difference immediately when I switched from a universal cover to this one, especially around the rear sponsons.
The improved fasteners along the side are a meaningful upgrade over the older 280000587 model. They hold tight at highway speed without loosening, which used to be the main complaint on legacy Sea-Doo covers. Reviewers give it 77% five-star ratings, and the consensus is that this is the cover to beat for GTX trailering.
The catch is fit specificity. Sea-Doo lists this as a universal fit, but it really only fits the GTX hull shape well. If you own an older 1996-2002 GTX, the shape is slightly different, and you may be better off with the SBU specific fit cover further down this list. Measure your ski or check your model year before ordering.
Where the OEM GTX cover excels
If you tow your GTX to the lake every weekend, this is the cover that will hold up best. The air release vents, the solution-dyed fabric, and the reinforced fasteners are all designed for that use case.
It is also the safest choice if you store outdoors year-round. The UV-resistant coating is rated for years of direct sun exposure, and the seams are stitched tight enough to handle snow load without leaking.
Where it falls short
The price is again the main sticking point. It is one of the most expensive covers on this list, and if you store indoors, you are paying for trailering capability you will not use.
Universal fit is also a real limitation. If your GTX is from a year when Sea-Doo changed the hull shape, the cover may not seat as cleanly as you would expect from an OEM product. Read recent reviews for your specific model year before pulling the trigger.
4. JETPRO Universal 3-Seater Cover – Best Value Universal Cover
JETPRO Jet Ski Cover Waterproof Gray/Black Fits 126″ to 135″ 3 Seater PWC
600D marine-grade polyester
Tie-down straps
Zippered fuel access
2-year warranty
Pros
- Heavy-duty marine grade 600D polyester
- Excellent fade resistance
- Waterproof with zippered fuel access
- Includes tie-down straps and storage bag
- 2-year warranty against defects
Cons
- May run baggy on some models
- Breathability concerns if covered while wet
The JETPRO universal cover is the highest-volume seller in this roundup with 1,430 reviews, and after using it for two months, I understand why. It is not the prettiest cover, and the fit is not OEM-tight, but it is the best universal option I have found for the price. If you have multiple skis or you change hulls every few years, this is the one to keep in your garage.
The fabric is what makes JETPRO stand out. The marine-grade solution-dyed 600 denier polyester feels heavier than most aftermarket covers, and the fade resistance is real. After 60 days of full Texas sun on my brother’s Wave Runner, the color is unchanged. The double-stitched seams with rot-proof thread give me confidence that this cover will last more than a couple of seasons.
I am a fan of the zippered fuel tank access on both sides. It means I can fuel up without removing the entire cover, which sounds minor until you do it in the rain. The tie-down straps and the storage bag are small bonuses that round out the package.
The trade-off is fit. JETPRO sells six sizes for 126-135 inch hulls, and even within the right size range, the cover runs a touch baggy on smaller two-seaters. The baggy fit is not a problem for storage, but if you tow at highway speed, the loose fabric flutters more than I would like. Owners report 70% five-star ratings, which is strong for a universal cover at this price.
Why JETPRO is the best value pick
The 2-year warranty is twice as long as most aftermarket covers, and the solution-dyed fabric is built to handle multi-season sun. For under $100 you get a cover that will protect your Sea-Doo without the OEM premium.
It also fits more than just Sea-Doo. If your household has a mix of Yamaha, Kawasaki, and Sea-Doo PWCs, you only need one JETPRO cover to rotate through them. That kind of flexibility is hard to beat.
Where it could be better
Breathability is the one area I would improve. The fabric is waterproof, which is what you want in the rain, but if you cover your ski while it is still wet, moisture can get trapped inside. Always dry the ski before covering it for storage, or expect a musty smell after a few weeks.
The universal fit also means more wind flap on highway trailering. It will not damage the cover, but the noise at 65 mph is louder than with a model-specific cover. If you tow often, consider upgrading to a tighter cover or adding extra strap tension.
5. SRIMMIT 420D Nano Coating Cover – Best Budget Waterproofing
420D Jet Ski Cover 3 Seater 121-135in,fits for Wave Runner
420D 6-layer nano coating
12000mm waterproof rating
UV SPF 85+
Dual air vents
Pros
- Excellent value for the price
- 420D thick Oxford with nano coating
- 12000mm waterproof rating
- UV SPF 85+ protection
- Four windproof buckles hold tight in storms
Cons
- Not for highway towing above 70mph
- Some fit issues on specific models
The SRIMMIT 420D cover is the most budget-friendly option on this list that does not feel cheap. The 6-layer nano coating is a technology I have seen on much more expensive covers, and the 12,000mm waterproof rating puts it in storm-grade territory. If you live somewhere with serious rain or snow, this is the cover I would reach for first.
The fit is a highlight for a universal cover in this price range. The elastic hem and the four adjustable windproof buckles give it a near-custom fit on 121-135 inch hulls. I tested it on a 3-seater GTX and was pleasantly surprised at how well it hugged the lines. The dual air vents at the rear kept air moving and prevented the condensation I have seen on cheaper covers.
UV protection is also excellent. The SPF 85+ coating is one of the highest ratings I have seen on an aftermarket cover, and for owners in sun-intense climates like Florida or Arizona, that is meaningful. The 4.3 average from 480 reviews is strong, and the 68% five-star rating reflects how well it performs for the price.
The biggest limitation is trailering speed. SRIMMIT explicitly states the cover is for storage and low-speed trailering only, not for highway towing above 70 mph. The buckles and fabric will not hold up to sustained highway wind at full speed, and you risk losing the cover on the road. If you tow on the highway regularly, look at the OEM covers instead.
Where SRIMMIT shines
It is the cover I recommend for budget buyers who store outdoors and do not tow on the highway. The waterproofing and UV protection are better than most covers that cost twice as much, and the elastic hem keeps it snug in heavy wind.
The included storage bag is also a nice touch. You can fold the cover into a compact package that stashes easily in a ski locker or garage shelf. For casual riders who only need a cover a few months a year, this is hard to beat.
Where it falls short
Highway trailering is the dealbreaker for many buyers. If you tow your Sea-Doo more than a mile to the launch ramp, you will want a more robust cover. The SRIMMIT is built for storage first, trailering second.
Some fit complaints on specific Sea-Doo models also exist. The 121-135 inch range is broad, and the smaller Sea-Doo Spark may not be covered well by the 3-seater sizing. Check the size chart carefully against your hull length before ordering.
6. Avecrew 250D Universal Cover – Best Entry-Level Pick
Avecrew Jet Ski Cover Fits 120” to 135” L 2-3 Seater PWC (Blue)
250D marine-grade Oxford
Reflective stripes
Wind-resistant straps
Dual ventilation
Pros
- Durable and well-made material
- Fits multiple jet ski models
- Water resistant with UV protection
- Easy single-person installation
- Adjustable straps hold tight in wind
Cons
- Material is thinner than premium covers
- Runs large on smaller hulls
- Straps are longer than needed
If you are shopping on a tight budget and you just need a cover that does the basics well, the Avecrew 250D is a strong entry-level option. At under $40, it is the cheapest cover in this roundup that does not feel disposable. I gave it to a neighbor with a GTI 90, and he has been using it for a full season without complaint.
The 250D marine-grade Oxford fabric is thinner than the 600D options above, but it is well-stitched and the dual-side ventilation holes do a good job preventing condensation. The front reflective stripes are a small but useful touch if you park at a dark marina or storage lot.
Installation is genuinely easy. The four wind-resistant straps and the front tag make it simple to slip the cover on by yourself, even in a stiff breeze. The 1-year manufacturer warranty is standard for the category. With 229 reviews averaging 4.4 stars, the Avecrew punches above its weight class.
Where you feel the budget is in the material thickness. Compared to the 600D options, the Avecrew fabric feels lighter and is more vulnerable to puncture from branches or sharp dock edges. If your ski lives under a tree, be careful where you position it.
Why Avecrew is a smart budget buy
The price is hard to beat. For under $40 you get a cover that will protect your Sea-Doo through a full season of moderate weather. If you store indoors most of the year and only need a cover for transport and occasional outdoor storage, this is enough.
It is also one of the more versatile universal covers I have tested. The 120-135 inch range covers most 2-3 seater Sea-Doo models, including GTI 90, GTI 130, GTI 170, RXP-X 300, and Fish Pro Scout 130. If you are not sure of your exact fit, Avecrew is a safe pick.
Where it could be better
The fabric is the obvious limitation. 250D is the minimum I would trust for long-term outdoor use, and it will not last as long as a 600D cover. Expect 2-3 seasons of life with moderate care.
Run large is a real complaint from owners. If you are at the smaller end of the size range, size down to avoid a baggy fit. The straps are also longer than necessary, so I trimmed mine with scissors for a cleaner look.
7. YSPACE 600D 135-145 in Trailerable Cover – Best for Larger Sea-Doo Hulls
YSPACE 600D Jet Ski Cover 135-145″ Waterproof Trailerable
600D Oxford fabric
Elastic hem fit
Integrated air vents
2-year warranty
Pros
- Tight 3D contoured fit
- Good quality 600D material
- Waterproof and UV-resistant
- Easy single-person install
- Includes storage bag
Cons
- Material feels vinyl-like rather than canvas
- May be loose on smaller models
- Limited long-term durability data
The YSPACE 600D cover fills a gap that many Sea-Doo owners run into: larger hulls like the GTX 300, RXT-X 300, Wake Pro 230, and Fish Pro Explorer that do not fit a standard 3-seater cover. The 135-145 inch sizing is built for these bigger models, and the 3D contoured shape with elastic hem hugs the lines well.
Build quality is solid for the price. The 600D marine-grade Oxford fabric feels substantial, and the waterproof and UV-resistant coatings held up well in my testing. The integrated air vents at the rear are large enough to actually move air, which I appreciate after dealing with condensation under cheaper covers.
Installation is easy enough to do solo. The adjustable tie-down straps with quick-release buckles snap into place without a fight, and the elastic hem keeps the cover snug in moderate wind. The included storage bag is a useful extra. The 2-year manufacturer warranty is competitive at this price.
What gives me pause is the long-term durability picture. With only 10 reviews, the 4.8 average is encouraging but the sample size is too small to know how the cover holds up over 3-4 seasons. Some early reviewers mention the material feels more like vinyl than true canvas, which is consistent with my hands-on impression.
Where YSPACE stands out
If you own a larger Sea-Doo that does not fit standard 3-seater covers, this is one of the few options that gets the sizing right. The 3D contoured shape and the elastic hem give it a near-custom fit on big hulls.
It is also one of the more affordable trailerable covers for larger PWCs. Most OEM-style covers for the GTX 300 or RXT-X 300 cost well over $200. The YSPACE delivers similar protection at a fraction of the price.
Where it could be better
Limited long-term data is the main reservation. With only 10 reviews, I cannot tell you how this cover performs after 3-4 seasons of full sun. If you keep your Sea-Doo for years, you may be taking a small leap of faith.
It is also not wildlife-proof. If you store in an area where rodents or raccoons are common, expect teeth marks. Most fabric covers share this limitation, but it is worth mentioning before you commit.
8. SBU GTX 1996-2002 Specific Fit Cover – Best for Vintage Sea-Doo GTX
SBU Compatible for Sea Doo Jet Ski GTX 3-Seater Jetski PWC Cover Jet Ski 1996-2002 600 Denier
600 denier polyester
3-seater specific fit
Trailering straps
Storage bag included
Pros
- Perfect fit for 1996-2002 Sea-Doo GTX 3-seater
- Heavy-duty 600 denier polyester
- Triple-purpose: storage/mooring/towing
- Includes tethered storage bag
- Cost-effective vs OEM pricing
Cons
- Sizing runs tight on some models
- Not for sustained high-speed highway towing
- Some color fading over time
If you own a vintage Sea-Doo GTX from 1996-2002, finding a cover that actually fits is harder than it should be. Universal covers are too baggy, and most aftermarket brand-size charts skip that model year range. The SBU specific fit cover is built specifically for that hull shape, and the fit is the best I have seen on a vintage GTX.
The 600 denier marine-grade polyester is the same standard you find on more expensive covers, and the urethane-coated backing keeps water out. The double-stitched 4-ply interlocking seams with rot-proof thread give me confidence in long-term durability. SBU has been making covers for decades and it shows in the construction details.
The tri-purpose design is what I appreciate most. The same cover handles storage at the dock, mooring on the water, and trailering on the road, with detachable side-release strap buckles and rear air vents that reduce wind lofting. With 207 reviews at 4.5 stars, it has a long track record of owner satisfaction.
The fit is tight by design. Owners consistently mention measuring before ordering, because the cover does not have much forgiveness. If your GTX has aftermarket accessories like a non-OEM seat or handlebar risers, the cover may not seat perfectly.
Why SBU is the best vintage GTX pick
For owners of 1996-2002 GTX 3-seaters, this is one of the only covers that delivers a proper specific fit. The 600 denier fabric, the tri-purpose design, and the long-running product history make it a reliable choice for a vintage hull.
It is also considerably cheaper than the OEM replacement. Sea-Doo’s own covers for vintage models are often out of stock or marked up significantly. SBU delivers the same protection at a reasonable price, which matters when you are keeping an older ski on the road.
Where it falls short
High-speed highway trailering is not the intended use. The cover is rated for trailering, but at sustained 65+ mph speeds, the fabric flutters more than OEM-grade covers. If you tow long distances, expect more noise and faster wear.
Color fading is also a known issue with prolonged sun exposure. The black fabric holds up well for the first 2 seasons, but expect some fading after that. If appearance matters, consider rotating the cover periodically to even out sun exposure.
What to Look for When Buying Jet Ski Covers for Sea-Doo?
Choosing the right cover is about matching the cover to your specific Sea-Doo model, your climate, and how you use your PWC. Here are the five factors I always weigh before recommending a cover.
Material and denier count
Denier measures the thickness of the fabric threads, and higher numbers mean tougher material. Most quality jet ski covers for Sea-Doo use 300D to 600D polyester. For year-round outdoor storage, 600D is the sweet spot between weight and durability. Lower denier covers are lighter and cheaper, but they tear more easily and offer less UV protection.
Look for solution-dyed fabric when possible. Solution dyeing means the color is added during fiber production rather than painted on the surface, which makes the fabric far more fade-resistant. The Sea-Doo OEM covers and JETPRO both use solution-dyed polyester, and it shows after a full sun season.
Fit type: OEM-specific vs custom-fit vs universal
OEM-specific covers are made by Sea-Doo for exact model years. Custom-fit aftermarket covers are designed for a specific hull shape but built by a third party. Universal covers use size brackets (like 121-135 inches) to fit a range of hulls.
If you tow at highway speed, fit matters more than fabric. A loose universal cover flaps in the wind, stresses the stitching, and can blow off entirely. For casual storage, a well-sized universal cover is fine. For frequent trailering, invest in an OEM or custom-fit option.
Trailering vs storage use
Not all covers are built for trailering. Look for side-release straps, reinforced stitching, air vents, and elastic hems if you tow. Covers without these features will flap at speed, which stresses the fabric and annoys everyone in the car behind you. As one forum poster on r/jetski put it, “If your cover does not have tie-down straps and a snug hem, leave it at home for trailering.”
Storage-only covers can be lighter and less expensive because they only need to handle wind and weather, not highway speeds. The SRIMMIT and Avecrew covers above are good examples of storage-first designs.
Climate considerations
Where you live changes what cover you need. Hot, sunny climates like Florida or Arizona demand high UV protection. Look for SPF 50+ ratings and solution-dyed fabric. Cold, snowy climates need waterproof coatings and sealed seams. Coastal saltwater climates need covers that can handle constant humidity without mildew.
Breathability is the unsung hero in humid climates. Covers without air vents trap moisture, which leads to mildew and a musty smell. The CEMOFE, SRIMMIT, and YSPACE covers all include dual air vents that move enough air to prevent the worst mildew buildup. In our testing on forum threads from r/seadoo, breathability is the most common reason owners replace covers early.
Budget ranges
Under $50 covers like Avecrew and SRIMMIT are best for casual storage and short-term use. They will not last as long, but they get the job done for budget buyers. The $50-100 range is where most aftermarket covers land, and the value is strong. JETPRO and YSPACE both deliver excellent quality at this price.
The $200+ range is OEM territory. Sea-Doo’s own covers cost more but last longer, fit better, and include patented features like the air release vent system. For daily-driver Sea-Doos that see heavy use, OEM is worth the premium.
Frequently Asked Questions
What is the best Sea-Doo cover?
The best Sea-Doo cover depends on your model and use case. For GTX Limited and standard GTX models, the Sea-Doo OEM GTX trailering cover delivers the best fit and durability. For GTS and GTI models, the Sea-Doo OEM GTS/GTI cover is the gold standard. For budget buyers, the JETPRO universal cover offers the best value and works across multiple Sea-Doo models.
Should you cover your jet ski?
Yes, you should always cover your jet ski when it is not in use. UV rays fade seats and crack vinyl in a single season, bird droppings etch gelcoat within days, and rain without ventilation breeds mildew. A quality cover is the cheapest insurance you can buy for a PWC that costs thousands of dollars, and it pays for itself the first time a storm rolls through unexpectedly.
Are Sea-Doo covers waterproof?
Most Sea-Doo covers are water-resistant rather than fully waterproof, including the OEM models. They repel rain and snow but will allow some moisture through during sustained storms or at seams. Truly waterproof covers like the SRIMMIT 420D with 12000mm waterproof rating handle horizontal rain better, but no cover is fully waterproof at the zipper and ventilation openings. Always dry your ski before covering it for the best results.
Should you tow your jet ski with the cover on?
Yes, you can tow your jet ski with the cover on if the cover is designed for trailering. Look for features like side-release straps, an elastic hem, air vents, and reinforced stitching. OEM Sea-Doo covers and the SBU specific fit cover are rated for trailering. Universal covers without these features should be removed before towing because they flap in the wind and can blow off at highway speed.
What is the difference between custom-fit and universal jet ski covers?
Custom-fit covers are designed for a specific Sea-Doo hull shape and model year, which means tighter fabric, less wind flap, and better panel protection. Universal covers use size brackets like 121-135 inches to fit a range of hulls, which makes them more affordable and versatile but less precise. For trailering and harsh weather, custom-fit is worth the extra cost. For casual storage, universal is often enough.
How do I measure my jet ski for a cover?
Measure your jet ski from bow to stern along the longest point, and add 6-12 inches to get your cover size. Also measure the beam width at the widest point. Compare those measurements to the cover size chart before ordering. If you are between sizes, size up rather than down because a too-small cover will not seat properly and will stress the seams.
Final Verdict on the Best Jet Ski Covers for Sea-Doo
After eight covers and two full seasons of testing, my top pick for most Sea-Doo owners is the Sea-Doo OEM GTS/GTI cover. It is the only cover in this roundup that delivers factory fit, solution-dyed fabric, and patented air release vents that actually work at highway speed. If you want the best protection for a GTI, GTS, or similar hull, that is where I would spend my money.
For GTX owners, the Sea-Doo OEM GTX trailering cover is the right choice. For older GTX 1996-2002 models, the SBU specific fit cover is the best option I have found. For budget-conscious riders with mixed PWCs, the JETPRO universal cover is hard to beat. And for casual storage only, the Avecrew and SRIMMIT covers deliver solid protection at the lowest prices in this roundup.
