Best Outboard Motor Cover for Storage and On-Water Use

#1 · Best Overall

1. Zettum Outboard Motor Cover 115-225 HP

• Material: Oxford Cloth
• Material Type: Oxford Cloth
• Compatible with Vehicle Type: Boat Outboard Motor

Best for: Large outboard storage cover.

Why it ranks #1: Its 600D Oxford cloth with PU coating and stated 31 x 23 x 29-inch size suit buyers seeking a full cover for larger 115-225 HP motors.

The 31-by-23-by-29-inch cover targets outboards rated 115–225 HP, giving owners of larger motors a defined size and power range to start from. Its 600D Oxford cloth with PU coating pairs a heavy-duty fabric with a waterproof barrier for covering an engine between outings or during storage.

The stated dimensions—31 inches long, 23 wide, and 29 high—make this a more concrete fit reference than horsepower alone, while the listing says the range suits most 115–225 HP motors. Its 600D Oxford cloth and PU coating provide the listed heavy-duty, waterproof construction, useful when the engine needs protection from wet conditions. Zettum also identifies compatibility with popular outboard brands, but measuring the motor remains important because the listing treats horsepower as a reference.

Skip it if you need a cover for a motor below 115 HP; Zettum’s up-to-25-HP cover suits a smaller outboard.

A sensible candidate for owners of larger outboards who want a waterproof, coated-fabric cover for storage or protection between trips. Its stated 115–225 HP range and dimensions are useful starting points, but the motor’s actual size still matters.

#2 · Best With Two-Year Warranty

2. Explore Land Outboard Cover 115-225 HP

• Material: 600D Marine Grade Polyester
• Material Type: 600D Marine Grade Polyester
• Compatible with Vehicle Type: Dinghy

Best for: Large outboard polyester cover.

Why it ranks #2: This 600D marine-grade polyester cover fits most 115-225 HP motors and lists a two-year warranty; measure carefully because it is universal fit.

The 31-by-23-by-29-inch dimensions give this Explore Land cover a practical fit reference for owners of most 115–225 HP outboards. Its 600D marine-grade polyester has a waterproof laminated undercoating, combining a heavy fabric with a water-resistant barrier for engine coverage between trips.

Explore Land names compatibility with brands including Honda, Tohatsu, Yamaha, Suzuki, Mercury, Evinrude, and Hangkai, which helps owners identify whether their engine make is among those listed. The cover’s 115–225 HP guidance and 31-by-23-by-29-inch dimensions narrow the fit check, but the seller cautions against relying on horsepower alone. A waterproof laminated undercoating on 600D marine-grade polyester supports protection when the covered engine encounters wet conditions.

Skip it if you need a cover for an outboard under 115 HP; Explore Land’s 50–115 HP version targets a smaller range.

Consider this for owners of larger outboards who want a laminated, waterproof cover and a broad list of named engine brands. Check the motor’s dimensions against the cover rather than choosing solely by horsepower.

#3 · Best 30-50 HP Fit Range

3. Zettum Outboard Motor Cover 30-50 HP

• Material: Oxford Cloth with PU coating
• Material Type: Oxford Cloth with PU coating
• Compatible with Vehicle Type: Boat

Best for: 30–50 HP engine storage.

Why it ranks #3: The listed 30-50 HP range and 600D Oxford cloth with PU coating make it a targeted full-cover option for many mid-size outboards.

For most 30–50 HP outboards, this Zettum full cover pairs a defined power range with 600D Oxford cloth and PU coating. The listed waterproof, heavy-duty, tear-resistant construction gives owners a coated fabric option for protecting an engine between outings or during storage.

The 30–50 HP range provides a useful first screen, while Zettum recommends checking motor circumference and height against its size chart to assess fit more closely. That step helps account for differences in engine shape within a power category. The 600D Oxford cloth with PU coating is described as waterproof, heavy-duty, and tear-resistant, supporting use as a full cover when the outboard is not in operation. Zettum lists compatibility with popular outboard brands.

Skip it if you need coverage for a motor above 50 HP; Explore Land’s 115–225 HP cover targets larger outboards.

Consider this for owners of 30–50 HP outboards seeking a waterproof full cover for storage or time between trips. Use the stated power range as a starting point and compare the motor’s circumference and height with the size chart.

#4 · Best for Motors Up to 25 HP

4. Zettum Outboard Motor Cover Up to 25 HP

• Material: Oxford Cloth with PU coating
• Material Type: Oxford Cloth with PU coating
• Compatible with Vehicle Type: Boat

Best for: Compact outboard full cover.

Why it ranks #4: Its stated fit for most motors up to 25 HP and 600D Oxford cloth with PU coating address buyers with compact outboards.

Zettum rates this full motor cover for most outboards up to 25 HP, giving small-engine owners a clear range for storage protection. Its 600D Oxford cloth with PU coating is listed as waterproof, heavy-duty, and tear-resistant, combining a coated shell with a full-cover format.

The up-to-25-HP guidance helps narrow the fit choice for compact motors, while Zettum advises checking circumference and height against its size chart. That measurement check matters because horsepower is not a complete description of an engine’s shape. The 600D Oxford cloth and PU coating are listed as waterproof and tear-resistant, making the cover relevant for protecting a motor between outings. Its full-cover format is intended for broader engine coverage than an on-water splash shield.

Skip it if you have an outboard above 25 HP; Zettum’s 30–50 HP cover targets a larger engine range.

This suits owners of small outboards who want a coated, waterproof full cover between outings. Its 25 HP limit defines the main use case, and the motor’s circumference and height remain important fit checks.

#5 · Best 50-115 HP Fit Range

• Material: 600D Marine Grade Polyester
• Material Type: 600D Marine Grade Polyester
• Compatible with Vehicle Type: Dinghy

Sized at 26 by 22 by 24 inches, this Explore Land cover targets most 50–115 HP outboards, giving smaller-engine owners a defined alternative to larger covers. The 600D marine-grade polyester and waterproof laminated undercoating provide a fabric-and-barrier combination for covering the motor between outings.

Explore Land lists compatibility with Honda, Tohatsu, Yamaha, Suzuki, Mercury, Evinrude, and Hangkai, so owners can check their engine make against the stated list. The 50–115 HP guidance and 26-by-22-by-24-inch dimensions offer useful starting points, while the listing warns that horsepower alone is not enough to establish fit. Its 600D marine-grade polyester with waterproof laminated undercoating supports use where wet-weather protection is a priority.

Skip it if you have an outboard above 115 HP; Explore Land’s 115–225 HP cover targets larger engines.

This is a practical match to consider for a 50–115 HP outboard needing a waterproof fabric cover. Its listed dimensions help with the fit check, but measure the motor because horsepower is not the only sizing consideration.

6. Zettum Outboard Motor Cover 100-140 HP

• Material: Oxford Cloth with PU coating
• Material Type: Oxford Cloth with PU coating
• Compatible with Vehicle Type: Personal Watercraft

Best for: Midrange outboard storage.

Why it ranks #6: Its 600D Oxford cloth with PU coating and stated 100-140 HP range offer a full-cover option, but the listing urges buyers to verify measurements.

A 600D Oxford shell with PU coating gives this Zettum cover a waterproof, tear-resistant construction for owners of motors in its stated 100–140 HP range. The full-cover format offers a way to shield the engine between outings, while the listed fit spans popular outboard brands.

The 100–140 HP range provides a first filter for matching the cover to an engine, and Zettum advises checking circumference and height against its size chart before purchase. That measurement step helps avoid relying on horsepower alone for fit. The 600D Oxford cloth and PU coating are listed as heavy-duty, waterproof, and tear-resistant, supporting use as an all-around protective cover. Its full-cover designation suits buyers seeking engine coverage when the boat is not underway.

Skip it if you have an outboard outside 100–140 HP; the Explore Land 50–115 HP cover targets a smaller motor range.

Choose this for a midrange outboard owner seeking a waterproof full cover with a defined power band. Before relying on that range, compare the engine’s circumference and height with Zettum’s size chart to assess the fit.

7. SeaSierra Outboard Motor Cover 150-225 HP

• Material: Oxford Fabric
• Material Type: Oxford Fabric
• Compatible with Vehicle Type: Boat, Outboard Motor

Best for: Large-engine weather protection.

Why it ranks #7: The 97.64 x 77.56-inch Oxford-fabric cover is intended for most 150-225 HP motors and lists a 90-day manufacturer warranty.

At 97.64 by 77.56 inches, this SeaSierra cover provides a large stated footprint for owners seeking coverage for most 150–225 HP outboards. Its PVC-coated Oxford fabric is described as tear-resistant and helps shield the engine from weather, debris, and scratches when covered.

SeaSierra lists compatibility with major outboard brands including Honda, Tohatsu, Yamaha, Suzuki, and Mercury, making the cover relevant across several common engine lines. The 97.64-by-77.56-inch dimensions and 150–225 HP guidance provide fit references, though the listing says horsepower is only a reference. PVC-coated Oxford fabric is described as tear-resistant and protective against wind, sand, rain, snow, scratches, and direct sunlight, supporting use during storage or when the engine is exposed.

Skip it if you own an outboard below 150 HP; SeaSierra’s 30–60 HP cover is intended for a smaller engine range.

This fits owners seeking broad weather and scratch protection for a larger outboard, especially across the listed mainstream brands. Use the dimensions as well as horsepower when judging fit, since the listing treats its horsepower guidance as a reference.

8. SeaSierra Outboard Motor Cover 30-60 HP

• Material: Oxford Fabric
• Material Type: Oxford Fabric
• Compatible with Vehicle Type: Boat, Outboard Motor

Best for: Small-to-mid outboard weather cover.

Why it ranks #8: Its 71.87 x 56.7-inch size targets most 30-60 HP engines; Oxford fabric with PVC coating is listed as tear-resistant.

SeaSierra’s 71.87-by-56.7-inch cover targets most 30–60 HP outboards, giving owners in that range a large-format cover with stated dimensions. The PVC-coated Oxford fabric is described as tear-resistant and helps protect the engine from weather, direct sunlight, and scratches.

SeaSierra lists compatibility with Honda, Tohatsu, Yamaha, Suzuki, and Mercury, among other mainstream brands. Its PVC-coated Oxford fabric is described as tear-resistant and protective against wind, sand, rain, snow, scratches, and direct sunlight, supporting coverage during storage or exposure to the elements.

Skip it if you own an outboard above 60 HP; SeaSierra’s 150–225 HP cover is intended for larger engines.

A relevant option for owners of 30–60 HP outboards who want a weather-protective cover in a defined size range. Check the listed dimensions against the engine, since the horsepower range alone does not establish the fit.

#9

9. GaiRen Outboard Motor Cover Up to 15 HP

• Material: Oxford Fabric
• Material Type: Oxford Fabric
• Compatible with Vehicle Type: Outboard Motor

Best for: Small motor all-weather cover.

Why it ranks #9: This cover is listed for outboards up to 15 HP and protection from weather and dust, but the supplied specifications give few fit details.

Rated for outboards up to 15 HP, this GaiRen cover gives owners of compact motors a stated upper limit to guide selection. Its thick polyester construction is described as waterproof and intended to shelter the engine from rain, wind, snow, dust, storms, tree sap, and pollutants.

The up-to-15-HP guidance makes this a narrowly targeted option for owners of small outboards rather than a general large-engine cover. GaiRen identifies Oxford fabric and describes the cover as thick polyester, with waterproof protection against varied weather. The listed protection also includes dust, tree sap, and pollutants, which is relevant when a motor is stored near trees or exposed to airborne debris. No cover dimensions are supplied here, so the stated power limit is the available fit reference.

Skip it if you have an outboard over 15 HP; Zettum’s up-to-25-HP cover serves a larger motor range.

This suits owners of compact outboards seeking a waterproof cover for protection from weather and everyday debris. Its main boundary is the 15 HP maximum, so it is not the right size category for a larger engine.

#10

10. Mercury Vented Splash Cover

• Material: Breathable Polysoft II® fabric, Cover…
• Material Type: Breathable Polysoft II® fabric, Cover…
• Compatible with Vehicle Type: 2.1L 115hp Pro XS, Outboard Engine

Best for: Running 115 Pro XS protection.

Why it ranks #10: Its vented design suits compatible Mercury engines while running, but it is a splash cover for on-water protection rather than a general storage cover.

A vented design lets this Mercury splash cover stay on while the engine runs, making it distinct from covers intended only for storage. It is specified for Mercury 2.1L 115HP Pro XS outboards and helps guard against water spray, UV exposure, and debris underway.

The venting is the key operational feature: Mercury says the cover can remain in place while running, fishing, and exploring, avoiding removal for those activities. Its breathable Polysoft II fabric includes mesh venting and is listed as UV- and water-resistant, supporting on-water protection from spray and sun exposure. The manufacturer describes a custom fit for the 2.1L 115HP Pro XS, so this application-specific cover is not a general substitute for a storage cover across other motor models.

Skip it if you need a cover for trailering or storage with the engine off; Mercury Tow-N-Stow covers are intended for those uses.

Choose this for an owner of a compatible Mercury 2.1L 115HP Pro XS who wants protection while boating with the engine running. Its specific fit is the key boundary; check the engine model before selecting it.
