Product Details

This aftermarket Outboard Motor Cover is designed for selected Mercury, Yamaha, and Honda outboard motors in the 30–60 HP range. It helps shield the engine cowling from sun, rain, spray, dust, and general marine debris during storage or transport. The Oxford-fabric construction has a water-repellent finish and a non-abrasive inner surface intended to help reduce scratching during normal use.

The universal-style shape is secured with an adjustable lower fastening system. Because cowling profiles and dimensions vary between brands, model years, and shaft configurations, confirm the cover dimensions and your engine's shape before ordering. The compatibility information below is a product-range guide rather than confirmation for every engine in a horsepower class.

  • Slip-on design for convenient installation and removal.
  • Heavy-duty Oxford fabric with a PVC water-repellent coating.
  • Adjustable drawstring, elastic hem, and buckles help hold the cover in place.
  • Suitable for protection during storage and transport when correctly fitted.

Engine Compatibility

This cover is intended for selected Mercury, Yamaha, and Honda outboards rated from 30 to 60 HP, including both 2-stroke and 4-stroke applications where the cowling size and profile are compatible. Horsepower alone does not guarantee fit. Check the engine brand, model, year, cowling dimensions, shaft arrangement, and fastening clearance before purchase.

Installation Notes

  1. Turn off the engine and allow it to cool completely before fitting the cover.
  2. Remove dirt, salt, and loose debris from the cowling so they are not trapped against the finish.
  3. Place the cover over the top of the outboard and pull it down evenly on all sides.
  4. Center the cover and check that the lower edge does not interfere with controls, hoses, or other components.
  5. Tighten the drawstring and secure the buckles or other fitted fasteners.
  6. For trailering, verify that the cover is fully secure and suitable for your transport conditions. Do not use a loose or damaged cover.

Care and Maintenance

Clean the cover with mild soap, a soft brush or cloth, and lukewarm water. Rinse with fresh water and allow it to air-dry fully before storage. Do not use bleach, harsh solvents, abrasive cleaners, or high heat. Store the cover dry and protected from prolonged direct sunlight when it is not in use.

Troubleshooting & FAQ

Will this cover fit my 50 HP Yamaha 4-stroke?

It may fit selected 50 HP Yamaha 4-stroke applications, but horsepower alone is not sufficient to confirm compatibility. Compare the cowling dimensions and profile with the listed cover dimensions before ordering.

Will it fit every Mercury, Yamaha, or Honda engine from 30–60 HP?

No. Engine dimensions, cowling shapes, shaft arrangements, and model generations vary. Use the compatibility guide as a starting point and verify your exact engine before purchase.

Can I use the cover while trailering?

The cover includes adjustable fastening features for transport, but suitability depends on the fit and transport conditions. Ensure it is tight, correctly centered, and free from loose or flapping material before travel.

How do I clean the cover?

Use mild soap, fresh water, and a soft brush or cloth. Rinse thoroughly and air-dry completely. Avoid bleach, solvents, abrasive products, and machine or high-heat drying.

When should I replace the cover?

Replace it if the fabric is torn, brittle, badly faded, water-repellent treatment has substantially deteriorated, or the fastening system no longer holds the cover securely.

Is this an OEM cover?

No. This listing is for an aftermarket replacement-style outboard motor cover. Brand and reference numbers shown on this page are comparison references and do not indicate OEM manufacture.

Safety & Important Information

  • Confirm your engine's brand, exact model, year, stroke, cowling dimensions, and shaft configuration before ordering.
  • Do not install the cover over a hot or running engine.
  • Do not use a damaged, loose, or incorrectly sized cover during transport.
  • Do not allow the cover or its fasteners to obstruct steering, controls, ventilation, fuel lines, or other engine components.
