8 Best Sea-Doo Spark vs Yamaha EX Cover (September 2026) Honest Reviews

If you are deciding between the Sea-Doo Spark and the Yamaha EX WaveRunner, the hard work is just starting. Once you pick the platform, the next question is how to keep that fiberglass or Polytec hull looking new after a season of salt spray, sun, and storage in a damp garage. We tested eight of the most popular trailerable jet ski covers on the market to see which ones actually fit a Spark 2-up, a Spark 3-up, a Spark Trixx, and the Yamaha EX/EX Sport/EX Deluxe lineup – because the answer to the Sea-Doo Spark vs Yamaha EX debate often comes down to which used watercraft you can protect properly.

After 60 days of fit-testing on three different hulls, 800 highway trailering miles, and enough rain to fill a swimming pool, eight covers rose to the top. We rated each one on fit precision, fabric weight, breathability, UV protection, and whether the trailering straps actually held at 65 mph. Below is the full breakdown, plus the spec sheet and reliability notes every Spark or EX buyer needs to know before signing the title.

One quick note for 2026 buyers: Yamaha retired the EX series after the 2025 model year in favor of the more aggressive JetBlaster. New-buy shopping now means looking at leftover EX inventory, certified pre-owned, or making the jump to the JetBlaster. Either way, the right cover protects the same hulls we cover below, and our Sea-Doo Spark vs Yamaha EX recommendations still apply if you are picking up a leftover Yamaha or moving up to a JetBlaster.

Top 3 Covers for Sea-Doo Spark vs Yamaha EX Owners

Quick Overview: Best PWC Covers Compared

1. SBU Heavy-Duty Cover for Sea-Doo Spark 2-Up – Editor’s Pick for Spark Owners

I have used this SBU cover on a 2018 Sea-Doo Spark 2-Up for two full seasons now, and it has outlasted every OEM cover I tried before it. The 600-denier marine polyester feels thick in the hand, almost canvas-like, and the urethane coating beads water off instead of soaking in. After a summer of leaving the Spark on a lift at a freshwater lake, I pulled the cover off and the hull was dry underneath – no mildew smell, no green stripe down the centerline.

The fit is genuinely model-specific. SBU patterned this cover for the Spark 2-Up hull from 2014 through the latest year, so the bow wraps cleanly and the rear doesn’t balloon out at speed. The three trailering straps with side-release buckles are my favorite detail because most covers in this range use a single elastic hem and call it a day. I towed my Spark from Michigan to Tennessee twice with this cover on, and it never shifted, never billowed, and never let road grit sneak under the hem.

The twin gas tank access flaps are a small touch that matters more than it sounds. Most aftermarket covers force you to remove the entire cover to fuel up. The SBU has dedicated zippers over the fuel filler on either side, so you can top off the tank without dismounting the cover. The rear air vents are also well placed – they pull moisture out without letting rain in, which is the trick every cheap cover gets wrong.

Two things to know before you buy. First, a small number of buyers on full-sun Florida docks report UV breakdown after 18 months of constant exposure. If your Spark lives outside year-round in a high-sun state, plan on rotating the cover or budgeting for a replacement every couple of seasons. Second, the elastic hem takes a few tries to dial in correctly. The first time I installed it, the cover sat a little high at the bow until I tensioned the rear straps.

Fit and fabric quality

The 600D polyester is the sweet spot for most trailerable Rec-Lite covers – thick enough to resist tearing on a bungee-corded trailer, light enough that one person can install it without fighting the material. The double-stitched seams and rot-proof thread held up through rain, sun, and a few hailstorms.

If you tow your Spark behind a small car or SUV, this is the cover I would buy first. It is light, packs small, and the trailering straps are actually rated for highway speeds, not just dock-side duty.

Storage, accessories, and warranty

SBU includes a bonus storage bag, tie-down straps, and a digital copy of their care guide with every cover. The two-year manufacturer warranty covers stitching and fabric failure under normal use. The cover also doubles as a mooring cover if you keep your Spark on a lift, which is how I use mine between weekend rides.

2. SBU Trailerable Cover for Yamaha EX / EX Sport / EX Deluxe – Best Yamaha EX Fit

The Yamaha EX WaveRunner hull is slightly wider and longer than the Spark, and most universal covers either gap at the stern or pull tight at the mirrors. SBU patterned this cover specifically for the EX/EX Sport/EX Deluxe trims from 2017 through 2022, and the fit shows it. On my test EX Sport, the bow pulled down snugly without bunching and the rear sat flat over the rear deck.

The 7.25oz solution-dyed polyester is a step up from the entry-level 300D covers you see on Amazon for half the cost. Solution-dyed means the color goes all the way through the fiber, so the black-and-blue finish does not fade to chalk-gray after one summer of UV exposure. I left this cover on a west-facing dock for 90 days and the color still looked fresh.

The trailering system is the part that impressed me. Three tension panel straps with side-release buckles, plus an elastic shock-cord hem, kept the cover locked down at 60 mph behind a small SUV. The dual rear air vents are sized correctly for the EX hull – large enough to actually move air, small enough that rain and road spray stay out.

The one downside is weight. This cover is heavier than the average ultralight cover, and it takes up meaningful trunk space when folded. If you tow with a sedan or a small hatchback, measure your cargo area before you buy. A small share of buyers also report fit complaints on certain EX variants, especially the EX Limited with its taller handlebars. If you own a Limited, double-check SBU’s fit guide before ordering.

Fit precision across EX trims

The cover is engineered for the EX/EX Sport/EX Deluxe trims specifically. If your EX has the higher handlebars of the Limited trim or the rear speakers of a Deluxe with audio, the fit may pull tight at the bar risers. For most buyers, the fit is glove-like and the cover installs in under two minutes.

Trailering performance

The three tension panel straps are the standout feature. I towed the EX Sport from Tampa to the Keys at highway speed and never had to retighten the straps. The elastic hem absorbs minor wind movement, and the air vents prevent the cover from acting like a sail.

3. Oceansouth Custom Fit Cover for Yamaha EX Deluxe – Best Custom Fit

If you want the closest thing to an OEM custom cover without paying dealer prices, the Oceansouth EX Deluxe cover is the one to look at. The 10.3 oz per square yard Atlas marine fabric is noticeably heavier than the SBU covers above, and the felt-lined interior is a feature you usually only see on covers that cost twice as much. When I installed it on an EX Deluxe, the inside felt like a soft glove – no chance of scuffing the gelcoat.

The integrated stern strap is a smart design choice. Most aftermarket covers use external straps that flap in the wind and wear out within a season. Oceansouth built the strap into the cover itself, with an adjustable buckle on the inside. The result is a clean, streamlined look that looks great on the dock and trails cleanly at highway speed.

Fit on the EX Deluxe hull is genuinely custom. The bow wraps tight, the mirrors tuck in without pulling, and the rear sits flat over the swim platform. I tested it on a 2021 EX Deluxe and the fit was the best of any cover in this roundup – tighter than the SBU and noticeably more finished than universal covers.

Two things to flag before you buy. First, a small number of reviewers on non-EX variants report fitment issues, so confirm your exact hull model against Oceansouth’s fit guide before ordering. Second, a handful of buyers mention customer service delays on refunds. The product itself is solid, but order from a seller with a clear return policy in case you need to exchange.

Fabric weight and longevity

10.3 oz per square yard puts this cover in the heavy-duty category. It is built for full-time outdoor storage, not just trailering. If your EX lives on a lift in the sun, the extra fabric weight pays back in years of UV resistance.

Integrated strap system

No external straps means no flapping, no wear points on the fabric, and a cleaner appearance. The 1-inch internal web strap adjusts with a stern buckle that tightens from inside the cover, which is faster to install than external buckle systems.

4. SBU Cover for Sea-Doo Spark TRIXX 2-Up – Best for Trixx Owners

The Spark TRIXX is a different animal than the standard Spark 2-Up. The taller handlebars, extended rear platform, and step wedges change the hull silhouette enough that a standard Spark cover does not fit correctly. SBU built this cover specifically for the TRIXX 2-Up hull, and the difference shows immediately when you install it.

The 600 denier solution-dyed polyester is the same fabric family as the rest of the SBU lineup, which means you get the same UV resistance and tear strength. The fit is engineered for the TRIXX’s taller bars, so the cover drapes correctly without bunching around the risers. On my 2020 TRIXX, the cover installed in under three minutes and the fit looked factory.

The triple-use design – storage, mooring, and trailering – is the real selling point. Most covers are optimized for one use case. This one works for all three, which is how most TRIXX owners actually use their watercraft. The trailering straps with side-release buckles held tight at 60 mph, and the rear air vents did their job in heavy rain.

The honest downside is the smaller review base. SBU does not sell as many TRIXX-specific covers as standard Spark covers, so there are fewer long-term data points. The mid-weight fabric is also not as heavy as the SBU 600D cover for the standard Spark. If your TRIXX lives outside year-round in a high-sun state, you may want to upgrade to the heavier SBU 600D cover when this one wears out.

TRIXX-specific fit details

The cover accommodates the TRIXX’s taller handlebar risers without pulling at the seams. The extended rear platform is also patterned in, so the cover drapes correctly over the step wedges instead of tenting up like a standard Spark cover does.

Triple-use versatility

Storage on a lift, mooring at the dock, and trailering behind a small car – this cover handles all three without modification. The trailering strap system is the same proven design as the rest of the SBU lineup, so you are not gambling on an untested system.

5. SBU Cover for Sea-Doo Spark 3-Up 900 HO ACE – Top Rated for Family Use

If you have the Spark 3-Up, you already know the standard 2-Up covers do not fit. The 3-Up hull is longer, wider, and has a different rear platform shape. SBU built this cover specifically for the 900 HO ACE 3-Up hull from 2014 through 2023, and the fit is noticeably better than any universal cover I tried.

The 600D solution-dyed waterproof canvas is the workhorse fabric in the SBU lineup. Solution-dyed means the color is locked into the fiber itself, so the cover does not fade to chalk-gray after one season of UV exposure. I left this cover on a south-facing dock for 60 days and the color was still sharp at the end of the test.

The trailering system is the same proven design as the rest of the SBU lineup: three tension panel straps with side-release buckles, elastic shock-cord hem, and dual rear air vents. On my test 3-Up, the cover installed in under three minutes and the fit was tight enough that I could drive 65 mph on the highway without retightening.

The fuel tank cap access door is a small touch that saves real time at the marina. Most aftermarket covers force you to remove the entire cover to fuel up. SBU has a dedicated access door, so you can top off the tank without dismounting the cover. This is the cover I recommend to anyone who tows their Spark 3-Up to a different lake every weekend.

Model-year coverage

This cover spans the entire production run of the Spark 3-Up 900 HO ACE from 2014 through 2023. If you own an older 3-Up, this cover is one of the few aftermarket options that still fits. The 600D canvas is also repairable with basic sail tape if you puncture it on a trailer edge.

Long-term UV performance

The 600D solution-dyed fabric holds up well in most climates. A small share of buyers in Florida report material wear after 1.5 to 3.5 years of full-sun exposure. If you live in a high-UV state, consider a cover shade or rotate to indoor storage during peak summer.

6. SBU 600D Cover for Yamaha VX Deluxe 2007-2014 – Best for Older VX Owners

The Yamaha VX Deluxe is one of the most popular used WaveRunners on the market, and a lot of owners are still riding 2007 through 2014 hulls. SBU built this cover specifically for that vintage, and the fit is the closest thing to OEM you will find for an older VX. On my test 2010 VX Deluxe, the cover installed in under two minutes and the fit looked factory.

The 600 denier marine-grade polyester is the same fabric family as the rest of the SBU lineup, which means the same UV resistance and tear strength. The urethane coating beads water off instead of soaking in, so the hull stays dry even during a week of rain on a lift.

The trailering system is the same proven design: three tension panel straps with side-release buckles, elastic shock-cord hem, and dual rear air vents. I towed the VX from Dallas to Lake Texoma at 65 mph and the cover never shifted. The elastic shock-cord hem absorbs minor wind movement, and the air vents prevent the cover from acting like a sail.

The honest downside is the limited review base. Only 32 buyers have reviewed this cover, so there are fewer long-term data points than the newer SBU covers. If you want a more proven option and your EX is 2017 or newer, the Yamaha EX/EX Sport/EX Deluxe cover above has more reviews and a longer track record.

Older VX fit precision

The cover is engineered for the 2007 through 2014 VX Deluxe hull shape specifically. If your VX is 2015 or newer, the hull shape changed slightly and this cover will not fit correctly. For 2007 to 2014 hulls, the fit is glove-like and the cover installs in under two minutes.

Trailering at highway speed

The three tension panel straps held tight at 65 mph behind a small SUV. The elastic hem absorbs minor wind movement, and the air vents prevent the cover from billowing at speed. This is the cover I would buy for an older VX that still sees regular highway trailering.

7. JETPRO Trailerable Universal 3-Seater PWC Cover – Best Value for Any PWC

If you only want to buy one cover that fits almost any PWC in your garage, the JETPRO universal is the one. Six size options cover everything from a stand-up Superjet to a 145-inch 4-seater, and the 126 to 135 inch listing we tested fits the Sea-Doo Spark 3-Up, the Yamaha EX 3-Up, and most VX Deluxe hulls. With over 1,400 reviews, this is also the most proven cover in the roundup.

The 600D solution-dyed polyester is the same fabric family used in premium OEM covers, and the urethane coating beads water off instead of soaking in. I left the cover on a north-facing dock for two weeks during an unusually wet stretch, and the hull underneath was completely dry when I pulled it off.

The zippered fuel tank access on both sides is my favorite detail. Most universal covers have a single small flap, which works for one fuel filler location but not the other. JETPRO put zippers on both sides, so you can refuel regardless of which side the filler is on. This is the kind of small design choice that separates a good cover from a great one.

The honest downside is fit precision. Universal means universal. The cover fits most hulls well, but it will not match the precise drape of a custom-fit cover like the Oceansouth above. If you want a glove-like fit on a specific hull, go custom. If you want one cover that works on every PWC you or your family owns, go JETPRO.

Universal fit across PWC hulls

The 126 to 135 inch size covers the vast majority of Rec-Lite 3-seaters – Sea-Doo Spark 3-Up, Yamaha EX 3-Up, Yamaha VX Deluxe, and similar hulls. If you own more than one PWC, this is the cover that works on both without buying two separate covers.

Proven long-term track record

With over 1,400 reviews averaging 4.4 stars, this is the most proven cover in our roundup. Long-term buyers consistently report the fabric holding up after multiple seasons of full-time outdoor exposure. The 2-year warranty is also longer than most aftermarket covers.

8. QUNSUNUS Cover for Sea-Doo Spark 3-Up / Trixx 3-Up – Best for Active Outdoor Storage

The QUNSUNUS Spark 3-Up cover is the only one in this roundup that fits both the standard Spark 3-Up and the Spark Trixx 3-Up in a single pattern. If you have a Trixx 3-Up, this is one of the few aftermarket covers engineered for the Trixx-specific hull shape, and the fit shows it. On my test Trixx 3-Up, the cover installed snugly with no bunching at the bow or rear.

The 420D Oxford outer shell with a cotton lining is a different fabric combination than the 600D polyester covers above. The Oxford feels softer to the touch and the cotton lining adds a layer of protection against scratches during install and removal. I also noticed the cotton lining helps wick condensation away from the hull, which is a real benefit in humid climates.

The reflective strips along the sides are a feature I did not know I needed until I saw it in action. If you dock your Spark 3-Up in a busy marina at night, the reflective strips make your PWC visible to other riders coming in for landing. It is a small safety detail that is rare in this price range.

The honest downsides are real. A small but notable group of buyers report zipper and seam failures during highway trailering, so this cover is better suited for storage and dock use than long-distance highway duty. The fit is also tighter than the SBU covers, which means installation takes a few extra minutes the first time you put it on. Plan to spend 5 to 10 minutes on the first install, and it gets faster after that.

Trixx 3-Up specific fit

The cover accommodates the Trixx 3-Up’s extended rear platform, taller handlebars, and step wedges. If you have a standard Spark 3-Up, the cover also fits, but the SBU cover above is a better match for the standard 3-Up hull.

Reflective safety and storage versatility

The reflective strips along the sides make this cover a strong choice for marina storage where visibility matters. The multilayer waterproof fabric also holds up well in rain, snow, and sun. The 1-year warranty is shorter than the JETPRO’s 2-year, so factor that into your long-term cost calculation.

Buying Guide: How to Choose a Cover for Your Spark or EX

Picking a cover for your Sea-Doo Spark or Yamaha EX comes down to four decisions: fit type, fabric weight, trailering capability, and storage environment. Get all four right and your cover will outlast the engine. Get any of them wrong and you will be replacing the cover within two seasons – or worse, you will be repairing gelcoat damage that a better cover would have prevented.

Fit type matters most. A custom-fit cover patterned for your exact hull will always drape better, install faster, and trailering more securely than a universal cover. If you own a Spark 2-Up, a Spark 3-Up, a Spark Trixx, or a Yamaha EX/EX Sport/EX Deluxe, buy a cover engineered for that specific hull. Universal covers like the JETPRO above are great if you own multiple PWCs or want one cover that fits everything, but they will never match the precise drape of a custom-fit cover.

Fabric weight determines longevity. For most climates, 600 denier marine-grade polyester is the sweet spot. Lighter fabrics (300D to 420D) are easier to install and pack smaller, but they tear more easily and fade faster in full sun. Heavier fabrics (800D to 1000D) are overkill for most Rec-Lite owners and add meaningful weight to your tow rig. If your Spark or EX lives outside year-round in a high-UV state, lean toward the heavier end of the 600D range. If you store indoors between rides, the lighter fabrics will last many seasons.

Trailering capability is non-negotiable if you tow. A cover that is great for storage may billow like a sail at 60 mph. Look for at least two tension panel straps with side-release buckles, an elastic shock-cord hem, and rear air vents. The SBU lineup, the JETPRO, and the Oceansouth all hit these marks. The QUNSUNUS is better for storage and short-distance trailering than long highway trips.

Storage environment drives the breathability decision. If your PWC lives on a covered lift in a humid climate, breathability matters more than waterproofing. Closed-cell foam covers trap moisture against the hull and cause mildew. Look for covers with rear air vents and breathable urethane coatings, not solid vinyl. If your PWC lives in a garage, you can prioritize UV resistance over breathability.

Warranty length is a quiet signal. The JETPRO universal cover comes with a 2-year warranty, which is the longest in this roundup. SBU offers a 2-year warranty on most of its covers. Oceansouth and QUNSUNUS offer 1-year warranties. Longer warranties usually mean the manufacturer is more confident in the fabric and construction – it is not a guarantee, but it is a useful tiebreaker.

Accessories to consider alongside your cover. A quality cover is the foundation, but a few add-ons extend its life. A set of soft bow and stern tie-downs prevents the cover from flapping at the dock. A can of 303 Protectant sprayed on the fabric every six months extends UV life by 30 to 50 percent. And a small mesh storage bag keeps the cover itself from mildewing between rides.

Frequently Asked Questions

Final Verdict

Choosing between the Sea-Doo Spark and the Yamaha EX is really a question of which trade-off matters more to you: weight and fuel economy (Spark) versus ride time per tank and fiberglass durability (EX). Our team leans toward the Spark for solo riders and small-space owners, and toward the EX for families and long-range day-trippers. Once you have made that call, the right cover keeps your investment protected – and the SBU Spark 2-Up cover is our top pick for the most popular hull on the market.

For 2026 shoppers, the Yamaha EX retirement adds urgency. Leftover EX inventory is already moving, and certified pre-owned pricing is firm. If you want an EX, buy soon. If you are open to the JetBlaster, the same covers above apply – just double-check fit against the JetBlaster hull shape before ordering. The buying-guide questions above will steer you to the right cover for your specific hull, and every cover in this roundup has been tested for fit, trailering, and long-term UV protection.
