Product Details

This full outboard motor cover is designed for small outboard engines in the 5–20 HP range. Made from waterproof 420D Oxford fabric with a PVC coating, it helps protect an engine from rain, sunlight, dust, dirt, and surface scratches during storage or transport.

  • Slip-on design for straightforward installation.
  • Drawstring closure helps secure the cover around the lower edge.
  • Water-resistant fabric helps shield the outboard from common outdoor conditions.
  • Includes a storage bag for convenient packing when the cover is not in use.

Engine Fitment Guidance

The cover is intended for outboard motors rated from 5 HP through 20 HP. Fit depends on the engine cowling shape and overall dimensions, so horsepower alone does not guarantee compatibility.

Installation Notes

Raise or tilt the outboard as appropriate for your storage or transport setup. Slide the cover over the engine cowling from top to bottom and check that it is seated evenly. Pull the drawstring at the bottom hem to tighten the cover around the motor, then secure the cord. Make sure the cover is not caught on controls, cables, sharp edges, or hot engine surfaces.

Before trailering, verify that the cover is firmly secured and that its use is appropriate for your towing conditions. Follow the boat and outboard manufacturer’s guidance for trailering.

Troubleshooting & FAQ

Will this cover fit my 15 HP 2-stroke motor?

The stated application range is 5–20 HP, but fit depends on the cowling dimensions and shape. Two-stroke and four-stroke engines can have different external profiles, so measure your motor and compare it with the 29 × 49 in cover dimensions before ordering.

Does horsepower alone confirm fitment?

No. Horsepower is only a general application guide. Confirm the cover dimensions, cowling shape, and the space needed for the drawstring closure before purchase.

Is this cover suitable for trailering?

The cover has a drawstring closure, but suitability depends on how securely it fits your engine and the conditions of transport. Tighten and secure the drawstring, and follow the outboard and boat manufacturer’s trailering recommendations.

How do I clean the cover?

Rinse with cool or clean water and use a soft brush for light dirt. Avoid harsh chemicals, abrasive cleaners, and excessive heat, which may damage the fabric or PVC coating. Allow the cover to dry completely before storing it in the bag.

When should I replace the cover?

Replace the cover if it develops significant tears, punctures, brittle or severely faded fabric, damaged seams, or a noticeable loss of water resistance.

Is this an OEM cover?

This is an aftermarket outboard motor cover. No specific OEM replacement number or brand-specific equivalence is established for this listing.

Safety & Important Information
