Product Details
This full outboard motor cover is designed for 100–150 HP Mercury, Yamaha, and Honda 4-stroke outboard engines. The Oxford polyester fabric with PVC coating helps shield the cowling from sunlight, rain, dust, spray, and surface scratches during storage or mooring.
The cover slips over the engine cowling and uses a zipper and bottom drawstring to help maintain a secure fit. Because outboard cowling shapes vary by brand, model, and year, compare your engine with the listed dimensions before ordering.
- Protective Construction: Oxford polyester fabric with a PVC coating helps resist exposure to weather and everyday marine contaminants.
- Secure Installation: A zipper and adjustable bottom drawstring help hold the cover in place around the cowling and lower motor area.
- Storage Convenience: The included storage bag keeps the cover compact and clean between uses.
- Broad Application: Intended for compatible 100–150 HP 4-stroke outboards from Mercury, Yamaha, and Honda; exact fit depends on engine dimensions and cowling design.

Troubleshooting & FAQ
Will this cover fit my specific outboard?
The cover is intended for compatible 100–150 HP 4-stroke Mercury, Yamaha, and Honda outboards. Since cowling dimensions differ between models and years, compare your engine with the cover dimensions of 24.4 × 14.17 × 19.3 inches before ordering. A horsepower rating alone does not guarantee a precise fit.
Is this cover suitable for trailering?
The cover is primarily intended for storage and mooring protection. For high-speed trailering, use a cover specifically reinforced and approved for trailering to reduce wind-whipping and possible damage.
How should I clean and maintain the cover?
Clean the cover with mild soap and lukewarm water using a soft cloth or brush. Rinse thoroughly and allow it to air dry completely before folding. Store it in the included bag only when dry. Avoid harsh chemicals, bleach, abrasive cleaners, and high-temperature drying that may damage the fabric or coating.
Is the material fully waterproof?
The PVC-coated fabric is designed to help shed rain and spray during normal storage conditions. It should not be treated as submersible or guaranteed waterproof under standing water, high-pressure spray, or prolonged exposure to severe weather.
What are the signs that the cover needs replacement?
Replace the cover if the fabric becomes thin, cracked, torn, or excessively faded, or if the coating flakes and the cover no longer fits securely. Inspect the zipper, seams, and drawstring regularly for wear.
Is this an OEM cover?
This is an aftermarket replacement cover. It is not represented as an original equipment cover or as an OEM-manufactured component.
Safety & Important Information
- Confirm the cover dimensions and cowling shape before ordering.
- Use the cover only when the engine is stopped and cool.
- Do not operate the engine with the cover installed.
- Do not use this storage cover as a substitute for a dedicated trailering cover.
- Remove the cover if moisture becomes trapped underneath and allow both the engine and cover to dry.
