Winter does a quiet kind of damage. A single season of wet snow, road salt, and UV-thin January sun can chalk gelcoat, pit aluminum, and embrittle exposed canvas before spring ever shows up. If you store outdoors, dry-dock, or trailer between cold weekends, a purpose-built cover earns its keep. The picks below split into two groups: full hull-and-motor covers for boats parked outside all winter, and dedicated motor covers for anglers who already have a cockpit cover but need to protect the lower unit and cowling. Every option here is built for real freezing, thawing, and wind cycles, not just a light autumn drizzle.

More Details On Our Top Picks
Generic “fits most outboards” covers usually end up billowing in the wind or pooling water near the cowling. The Oceansouth Custom Fit Cover takes a different route: it’s tailored to a specific Mercury 75-115HP four-stroke platform from 2014 onward, with five leg-length options running from 15″ through 35″. That kind of model-level cut matters in winter, when even a small loose flap can channel wind under the fabric and sandblast the paint over a frozen month.
Owners running a matching motor get a snug fit that the elasticized hem and twin rope cleat pull tight. Felt lining on the inside protects the cowling finish from abrasion during install and removal. For anyone whose boat sits outside through a New England or Great Lakes winter, this is the kind of cover you can leave on without checking weekly.
Where It Excels
- Custom-tailored geometry reduces flapping and water pooling around the cowling.
- Five leg-length options let you dial in fit for short, mid, and extra-long shafts.
- Soft felt inner lining shields painted surfaces from scuffs on cold mornings.
- Designed for a popular Mercury range, so most mid-power anglers own a compatible motor.
Things To Consider
- Model-specific, so it won’t transfer if you sell the boat and upgrade to a different brand.
- You may find the cover slightly stiff below freezing, so a few warm-up minutes in a garage help installation.
Key Specs
Built With In Mind
Owners of a Mercury 75-115HP four-stroke from 2014 onward who store outdoors or on an unheated lift through a snowy winter.
Skip It When
You run a different brand or older motor. The Oceansouth Universal Full Outboard Motor Cover is a smarter fit when your hardware does not match this Mercury range.
Where the Oceansouth Custom Fit Cover plays one model very precisely, the Oceansouth Universal plays the field. Five size buckets cover everything from a 3.5hp kicker up to a 250hp main, with the 8hp-20hp variant hitting the sweet spot for jon boats, tenders, and small fishing rigs. That’s the configuration that fits the most common small-boat winter storage scenarios.
The cover wraps the full motor, cowling to skeg, in UV-resistant marine fabric with reinforced stitching. Heavy-duty means it in the spec-sheet sense: built for long outdoor exposures where a thin tarp would chalk and tear within a season. For most weekend skippers with a small outboard on a stored jon boat or dinghy, this is the workhorse option.
Reasons It Performs
- Five size tiers, from 3.5hp up to 250hp, cover nearly any common outboard.
- Full-body wrap shields the cowling, mid-section, and lower unit from salt and ice.
- Reinforced stitching holds up through repeated freeze-thaw cycles.
Points To Note
- Universal sizing means a slightly looser fit than the Oceansouth Custom Fit Cover on Item 1, so expect to spend extra time tightening the hem.
- The 8hp-20hp version is one bucket in a range, so measure your motor’s height before ordering to avoid sag at the skeg.
Whose Shelf It Belongs On
Small-boat owners running an 8hp-20hp outboard who need a universal, all-season cover and don’t want to special-order by model.
Look Elsewhere When
You own a Mercury 75-115HP and want a cover that hugs every contour. The Oceansouth Custom Fit Full Cover for Mercury Outboard Engine is the better match for that crowd.
Small bass boats tend to suffer the most from ill-fitting covers, since the low freeboard and exposed trolling motor leave a lot of hardware exposed to wind-driven snow. The Tegnero 1200D fits hulls from 14′-16′ with a beam up to 68″, which covers the popular 14-foot Bass Tracker and Tracker-style rigs that get parked at the end of every fall.
The cover ships with both a hull section and a motor section, so you get full protection in one bundle. A 1/4-inch elastic cord runs the full hem and 11 quick-release straps tie down for trailering. That makes it a good match if your “winter storage” actually means an uncovered tow to a cabin or a friend’s barn.
Noteworthy Benefits
- Bundled motor cover means you don’t piece together a separate outboard cover mid-winter.
- Eleven quick-release straps keep the cover anchored during wind gusts on a trailer.
- 1200D fabric density handles UV and abrasion better than lighter 600D alternatives.
Trade Offs
- Designed for V-hull, tri-hull, and pro-style bass boats only, so it does not suit deep-V or cathedral-hull fishing rigs.
- Gray color shows grime and pollen lines more than black covers on the Tegnero 16-18.5ft and 17-19ft variants later in this list.
Best Suited To
Owners of small bass or Bass Tracker rigs 14-16 feet long with beam up to 68″ who trailer to seasonal storage and want everything in one package.
Consider Something Else When
Your hull pushes past 16 feet. The Tegnero 1200D Bass Boat Cover 16-18.5ft with Motor Cover covers that segment with a wider beam allowance.
The 16-18.5ft range is the most common bass boat size, so this Tegnero variant hits the volume center of the market. It accepts hulls up to 94″ wide, which is the wide-beam territory where many aluminum rigs sit. Black fabric absorbs heat, which sounds like a downside, but it actually helps evaporate residual moisture before it freezes under the cover during shoulder-season swings.
The same 1/4-inch elastic hem and 11 quick-release strap system appears here, giving a familiar install and tension pattern for anyone moving up from a smaller 1200D cover. It’s a solid step up from the 14-16ft version when your rig finally graduates to the next size class.
The Value In It
- 94″ beam allowance fits wider bass hulls that the 14-16ft Tegnero cannot.
- Black color hides grime better than the gray 14-16ft option.
- Same strap and elastic layout as the smaller Tegnero, so the install feels familiar.
Small Caveats
- At 1200D, this is heavy. Lifting and folding the cover on a wet dock takes effort.
- You may want to double-check bow height against your tallest storage rafter before ordering.
Made For
Mid-size bass boat owners in the 16-18.5ft range who want one of the more universal fit profiles in this roundup.
Not Your Match When
Your hull tops 18.5 feet or you need a 96″+ beam. The Tegnero 1200D Bass Boat Cover 17-19ft with Motor Cover is a smarter pick for that profile.
Jon boats live a different life than bass boats. Flat bottoms, low gunwales, and often a tiller-driven outboard on the back mean wind has nothing to grab but flat canvas. The NOOKAT 12ft Jon Boat Cover fits hulls 10-12 feet long with a beam up to 56″, and pairs with a motor cover for full coverage. The 1200D marine polyester shell is the same density class as the Tegnero picks, so durability feels comparable.
Extra reinforcement at the front and rear panels protects the high-wear zones where canvas meets the transom and bow. For a hunter or fisherman who parks a jon boat under trees all winter, that reinforcement matters where debris tends to settle.
A Strong Showing
- Reinforced bow and transom panels address the most common wear points on jon boat covers.
- 1200D polyester resists tearing from wind better than lighter 600D or 800D alternatives.
- Includes a separate motor cover for full-boat coverage in one package.
Honest Caveats
- Only sized for 10-12ft hulls, so larger jon boats need a different selection.
- Flat-bottom jon boats can collect standing water on the cover if the bow sags, so check tension after major snowfalls.
Who It Suits Best
Hunters, anglers, and property owners with 10-12ft jon boats stored outdoors or under partial cover.
A Better Fit Elsewhere
You run a 14-16ft bass hull instead of a jon boat. The Tegnero 1200D Bass Boat Cover 14-16ft with Motor Cover matches that geometry better.
Solution-dye is the technology to notice here. Standard polyester fabric is woven first and dyed afterward, which means the color sits on the surface and fades under UV. Solution-dye injects pigment into the fiber before extrusion, so the color runs through the yarn. That matters for a cover that sits through months of low winter sun, especially at southern latitudes where UV keeps working through January.
The BOATPRO 17-19ft cover uses this fabric at 1200D density, with double-needle stitching and PU-reinforced seam tape that blocks water migration at the joints. Combined with the bundled motor cover, this is a good fit for owners who want the same boat in the same driveway for years without watching the cover chalk out.
Real Benefits
- Solution-dyed fabric resists UV fading longer than surface-dyed alternatives.
- Double-needle stitching with PU seam tape keeps water from wicking through joints.
- Bundled motor cover eliminates the “I forgot to cover the lower unit” risk.
Less Ideal Details
- 17-19ft sizing lands in a narrow band, so measure your hull including bow pulpit before ordering.
- You may find the heavier solution-dyed fabric slightly stiffer to fold than lighter covers, which matters for off-season storage in a small garage.
Key Specs
Perfect Match For
Owners of 17-19ft V-hull, tri-hull, or runabout boats in sunny or high-elevation climates where UV is relentless even in winter.
Reach For A Different Pick When
Your hull is in the 16-18.5ft band instead. The BOATPRO 1200D Waterproof Boat Cover 16-18.5ft with Motor Cover covers that range with the same fabric system.
Same fabric recipe as the 17-19ft BOATPRO, sized down for the most popular runabout class on the water. 16-18.5ft V-hulls, tri-hulls, and bass boats all fit within the cut, and the beam allowance reaches 68″ to handle wider hulls in that range. For most families with a single recreational boat, this is the size they actually own.
The PU seam tape is the under-appreciated detail. Stitching without tape is the most common failure point on cheaper covers, since water migrates through the needle holes and pools on the deck. This one stops that path, which is exactly what you want during a January thaw-freeze cycle.
A Few Strong Suits
- Seam tape and double-needle stitching stop the slow wicking that ruins cheap covers.
- Solution-dyed 1200D fabric keeps color and strength stable over multiple winters.
- Trailerable design means it stays put during transport between storage and launch.
Points To Keep In Mind
- Black color absorbs summer heat, so if you also use the cover in shoulder seasons, the cabin can get warm at midday.
- Beam tops out at 68″, which excludes very wide beam boats in this length range.
Right Fit For
Owners of 16-18.5ft runabouts, V-hulls, and tri-hulls who want a winter-rated cover they can also leave on during spring transport.
Where Another Pick Suits Better
You run a smaller 14-16ft rig and don’t need the extra length. The Tegnero 1200D Bass Boat Cover 14-16ft with Motor Cover is the more tailored option there.
1300D is one density tier above the 1200D fabric on most of the other picks, which puts the Kipiea in the “built for punishment” category. It’s a full-motor cover, so it slips over the cowling and lower unit on small outboards in the 2-15HP range, with 66″ of circumference and 52″ of height to fit a wide swath of kickers and trolling-style engines.
If you already have a full hull cover and just need to protect the exposed motor, this solves that problem without buying a second cover system. The 1300D shell holds up under trailer wind, salt spray, and UV that would fray a thinner fabric by mid-winter.
Practical Advantages
- 1300D outer shell out-tears most 1200D and 600D alternatives.
- Trailerable design keeps the cover secured at highway speeds.
- Universal sizing across the 2-15HP bracket simplifies ordering.
Practical Considerations
- Universal sizing means you should measure your motor’s actual height and girth, not just trust the horsepower bracket.
- Standalone motor cover only, so you’ll still need a hull cover if you store the whole boat outside.
Key Specs
Who Should Grab It
Owners with a 2-15HP outboard who already have hull coverage but want dedicated, heavy-duty protection for the engine.
Swap It Out When
You need full-boat coverage including hull and motor. The Tegnero 1200D Bass Boat Cover 17-19ft with Motor Cover bundles both in one package.
Same Tegnero build as the 14-16ft and 16-18.5ft versions, scaled up to 17-19ft hulls with a beam up to 96″. That wide beam allowance matters for pro-style bass boats with elevated casting decks, which can push past the 68″ and 94″ limits of the smaller Tegnero sizes. If your boat sits in a covered slip or open field all winter, the wider beam cut is the difference between a snug cover and one that gaps at the chines.
The 11 quick-release straps and full elastic hem work the same way as on the smaller Tegneros, so installation feels consistent if you’ve owned one before. It bundles a motor cover, so you get hull and engine protection in a single order.
Notable Upsides
- 96″ beam allowance fits wider bass boats the smaller Tegneros cannot.
- Bundled motor cover saves a separate purchase and matching hassle.
- Eleven straps distribute load across the hull to reduce stress points.
Some Limits To Know
- Larger size makes the cover heavier to handle solo in winter winds.
- Designed for V-hull, tri-hull, and pro-style boats, so it does not fit deep-V or cathedral hulls.
The Right Fit
Owners of 17-19ft bass, Bass Tracker, or pro-style fishing boats with up to 96″ beams who need a winter cover that goes on and comes off with one helper.
Another Choice May Suit
You want solution-dyed color retention for long-term UV exposure. The BOATPRO 1200D Waterproof Boat Cover 17-19ft with Motor Cover delivers the same size range with that fabric upgrade.
Color is the headline on this one. Gray reflects more solar heat than the black BOATPRO variant on Item 7, so the cabin stays cooler during those random warm spells in February and March. For owners in the South or Southwest where the sun stays strong all winter, that temperature control can prevent cockpit vinyl from getting hot enough to warp under the fabric.
Underneath the color, it’s the same 1200D solution-dyed build with double-needle stitching and PU seam tape. Size targets 16-18.5ft V-hulls, tri-hulls, and runabouts. For a boat in a sunny climate, this is the version to reach for over its black sibling.
Useful Highlights
- Gray fabric reflects solar heat, which protects interior vinyl during sunny winter days.
- Solution-dyed fibers resist fading despite the lighter color showing UV exposure more visibly.
- PU-reinforced seams and bundled motor cover round out a complete protection package.
Where It Is Less Suited
- Gray color shows dirt and pollen lines more readily than the black BOATPRO 16-18.5ft version.
- You may want to budget extra time for periodic cleaning to keep the lighter cover looking sharp.
Who Will Love This
Owners in warm, sunny winter climates who run 16-18.5ft V-hulls or runabouts and want a heat-reflective alternative to black covers.
Wrong Turns To Avoid
You’re storing in a snowy northern climate where heat reflection matters less than heat absorption for melting frost. The black BOATPRO 1200D Waterproof Boat Cover 16-18.5ft is the more practical pick in that setting.
What To Weigh Before Choosing Boat Covers For Winter Storage
Match the cover to the hull, not the other way around
Measure your boat’s length on the centerline and the beam at the widest point before browsing. Manufacturers list ranges like 16-18.5ft, but those ranges assume a typical beam for the length. A wide-beam 17-footer needs a cover rated for at least 90″ of beam, while a narrower fishing rig might wear the same length cover at 68″. Mismatched sizing is the most common cause of pooled water and torn panels mid-winter.
Think about the motor before buying a hull cover
Some covers bundle a motor cover, and some do not. If your outboard sits exposed above the cowling line, a hull cover alone leaves the lower unit vulnerable to ice, salt, and rodent damage. Bundled kits like the Tegnero 1200D Bass Boat Cover 14-16ft with Motor Cover or the BOATPRO 1200D Waterproof Boat Cover 17-19ft with Motor Cover save the step of matching a separate cover later.
Pay attention to fabric density and seam construction
Denier (the “D” number) measures fiber density, and 1200D sits comfortably above the cheap 600D covers sold at big-box stores. Solution-dyed fabric goes further by locking pigment into the yarn, so the cover holds its color through multiple winters. Double-needle stitching with PU seam tape blocks water migration, which is the slow killer of otherwise decent covers.
Trailered storage adds real requirements
A cover that only has to survive a stationary winter needs less anchoring than one that also sees highway miles. Quick-release straps, elastic hems, and reinforced tie-down points all matter if your winter routine includes hauling the boat to and from storage. Most of the picks above are trailerable, but it’s worth confirming before checkout.
Key Considerations Across These Picks
Common Shopping Slip Ups
The most common error is ordering by horsepower alone on universal motor covers. A 15HP motor can have very different dimensions depending on shaft length and cowling style, so the Kipiea 1300D Outboard Motor Cover’s note to measure the actual circumference and height is the right instinct. Another frequent miss is buying the lightest cover available to save money, only to watch it tear after a single windy January. Stepping up to a 1200D or 1300D shell usually pays back in one winter of avoided replacement.
The Case For Spending Up
Higher-tier covers earn their keep through fabric upgrades and seam engineering. Solution-dye, PU seam tape, double-needle stitching, and reinforced stress points all add up to a cover that survives multiple winters instead of one. For a boat kept outdoors in a four-season climate, the difference between a budget cover and a tier-up cover often shows up as the difference between re-covering next fall and not thinking about it for years.
Frequently Asked Questions
Do boat covers need to be breathable for winter storage?
A fully waterproof cover is fine for winter as long as the boat is dry underneath when you install it. Trapped moisture is what causes mildew and freeze damage, not the cover itself. A dry boat under a waterproof cover is the goal.
Should I leave the motor tilted up under the cover?
Tilting the outboard up keeps the lower unit out of pooled water and reduces the surface area exposed to ice. Most covers in this roundup accommodate a tilted motor, but the Kipiea 1300D Outboard Motor Cover and the bundled motor covers on the hull-and-motor combos are designed to wrap a tilted cowling cleanly.
Can I use a boat cover while trailering on the highway?
Trailerable covers like the Tegnero 1200D Bass Boat Cover 17-19ft and the BOATPRO 1200D Waterproof Boat Cover 17-19ft include strap systems specifically for transport. Always re-tension straps before each tow, and double-check that bow and transom straps are secured so the cover cannot lift at speed.
How long do 1200D boat covers typically last?
In four-season outdoor exposure, a quality 1200D cover with reinforced seams generally lasts several winters before the fabric shows noticeable wear. Solution-dyed versions like the BOATPRO 1200D Waterproof Boat Cover 17-19ft often outlast surface-dyed alternatives because the color and fiber degrade together rather than the color fading first.
Is a separate motor cover worth it if the hull cover includes one?
Bundled motor covers handle the basics, but dedicated motor covers like the Kipiea 1300D add higher denier fabric for owners in particularly harsh climates. If your boat sits in a windy, exposed slip, the standalone motor cover adds margin where it matters most.
Wrap Up
Winter storage isn’t glamorous, but it’s where boats either survive or quietly fall apart. Match the cover to the hull length and beam, decide whether you need bundled motor coverage or a dedicated motor cover, and don’t underspend on fabric density if your boat lives outside. The right cover pays you back every spring with a cleaner boat and a faster launch.
