The right inboard boat engine cover depends on whether the engine is exposed or enclosed in a compartment. Of the products listed here, the Loomcraft cover is the only one described as fitting inboard/outboard motors; the other four are outboard covers and should not be treated as covers for an enclosed inboard engine. Check engine dimensions and cover style before buying. The SavvyCraft is sized for 60–90 HP outboards, while the Zettum options cover different outboard size ranges.

Loomcraft 600D Inboard/Outboard Cover
Best for: Buyers looking for a cover specifically described for standard inboard/outboard motors. Its 600D Oxford fabric is listed as waterproof and UV-protective, and the reflective strip can improve visibility when a covered boat is moored in low light.
The product is described as protecting against sunlight, rain, dirt, and pollutants. It is the closest match to the inboard/outboard search, so it is included ahead of covers explicitly sized for outboards only.
Limitation: The listing does not provide exact cover dimensions. Confirm the engine’s shape and measurements with the seller before purchasing, especially for an enclosed inboard engine.
SavvyCraft 60–90 HP Outboard Cover
Best for: Owners of outboard motors in the stated 60–90 HP range who want a full-size cover with closure features. The listing gives a circumference of up to 76 inches and height of up to 65 inches, plus a drawstring and heavy-duty zipper for fitting and removal.
The cover uses marine-grade 600D polyester and is described as waterproof, breathable, and UV-treated. Reinforced construction at the skeg end and double-stitched seams are also listed.
Limitation: This is an outboard cover, not a general cover for an enclosed inboard engine. Measure the motor; horsepower alone does not ensure a fit.
MY RUSTIC 50–115 HP Outboard Cover
Best for: Outboard owners seeking a cover with ventilation and adjustable securing features. The listed size is 26 × 22 × 24 inches, and the stated fit range is 50–115 HP. A rear air vent is intended to add ventilation during longer storage.
The cover is made from 600D marine-grade polyester with a waterproof undercoating. A quick-release buckle, elastic cord, and two click-close straps provide several ways to secure it.
Limitation: Its outboard-specific shape and size make it unsuitable to assume a fit over an inboard engine or engine compartment.
Zettum 50–115 HP Outboard Cover
Best for: Buyers who need a compact cover for an outboard listed in the 50–115 HP range. Zettum specifies dimensions of 26 × 22 × 24 inches and describes the material as 600D Oxford cloth with a PU coating.
The listing says the fabric is waterproof, breathable, and designed to help shield a motor from sun, dust, mist, and dirt. The product is selected as another clearly specified outboard option for comparison.
Limitation: Zettum notes that horsepower is a reference only and recommends measuring the motor. Do not use the horsepower range as a substitute for checking dimensions.
Zettum 115–225 HP Outboard Cover
Best for: Owners of larger outboards who need the larger of the two listed Zettum sizes. It measures 31 × 23 × 29 inches and is described as fitting many motors in the 115–225 HP range.
Like the smaller version, it uses 600D Oxford fabric with a PU coating and is described as waterproof and breathable. Choose this over the 50–115 HP version only when the larger dimensions match the motor.
Limitation: This product is explicitly an outboard cover. It is not identified as suitable for an inboard engine or a full engine compartment.
Buying Guide: How To Choose An Inboard Boat Engine Cover
Is the engine inboard, inboard/outboard, or outboard?
Identify the engine layout before comparing covers. An inboard engine is typically housed inside the boat, while an outboard motor is mounted at the stern. An inboard/outboard setup has a different exposed configuration from an enclosed inboard engine. Product titles and fit descriptions matter: a cover sized for an outboard may not fit an engine compartment or an inboard/outboard assembly.
Which measurements should you check?
Measure the engine or exposed motor where the cover will sit, including its length, width, height, and circumference if the listing specifies it. Compare those numbers with the product’s stated dimensions. Treat horsepower ranges as a rough guide, not proof of fit; the Zettum listings explicitly recommend measuring the motor.
What fabric and closure features matter?
Compare the listed material and coating with the conditions where the boat is stored. The products here describe 600D polyester or Oxford fabric, with waterproof or UV-protection claims varying by listing. Drawstrings, zippers, elastic cords, and buckle straps can help secure a cover. A vent may be useful for storage, but follow the product instructions for ventilation and moisture management.
Should an engine cover be used while the engine is running?
Do not assume a storage cover is safe during operation. These listings describe protective covers, not operating covers. Remove the cover before starting or running the engine unless the manufacturer explicitly states otherwise.
Frequently Asked Questions
Can an outboard motor cover fit an inboard engine?
Not necessarily. Outboard covers are shaped and sized for exposed motors. Check the listing for explicit inboard compatibility and verify the measurements before buying.
Which listed cover is described for inboard/outboard motors?
The Loomcraft listing says it fits standard inboard/outboard motors. It does not provide exact dimensions in the supplied product details, so confirm fit before purchase.
Is horsepower enough to select the right cover?
No. Horsepower ranges are guides, not dimensional guarantees. Measure the motor and compare the measurements with the cover specifications.
What features can help protect an engine in storage?
Water-resistant material, UV-protective fabric, and a secure closure can help shield a covered engine from weather and dirt. Choose features that match the product’s intended engine type and storage conditions.
Do the listed products cover an entire inboard engine compartment?
The product details do not establish that any listed cover fits an entire inboard engine compartment. Confirm the intended coverage area and dimensions with the manufacturer or seller.
