Product Details

This Sea Sierra Outboard Motor Cover is designed to help protect 5–30 HP outboard engine cowlings from water, sunlight, weather exposure, and scratches. The cover uses a universal drawstring design intended for use with many outboard engines in this horsepower range, including selected Mercury, Yamaha, and Honda models.

Because cowling dimensions and shapes vary by engine, compare your engine's measurements with the cover dimensions before ordering. Horsepower and brand alone do not guarantee fitment.

  • Slip-on installation with an integrated drawstring closure for a more secure fit.
  • Durable Oxford Fabric with a PVC coating for water-resistant, UV-resistant, and general weather protection.
  • Helps shield the cowling from dust, light moisture, sun exposure, and surface scratches during storage.
  • Package includes one outboard motor cover.

Engine & Model Compatibility

This cover is intended for many 5–30 HP outboard motors. Confirm the cowling dimensions and shape before purchase, especially when selecting a specific model from Mercury, Yamaha, Honda, or another manufacturer.

  5. Confirm that the cover does not interfere with controls, ventilation openings, or other equipment before use.

Troubleshooting & FAQ

How do I know if this cover will fit my specific engine model?

The cover is intended for many 5–30 HP outboard motors, but horsepower and brand do not determine fit by themselves. Measure the engine cowling and compare it with the listed cover dimensions of 19.7" × 11.8" × 15.7" (50 × 30 × 40 cm). Also check the cowling shape and the location of any handles, controls, or protrusions.

Can I use this cover while trailering my boat?

The drawstring helps hold the cover in place, but this product should not be treated as a guaranteed high-speed trailering cover. If you use it during transport, secure it carefully, confirm that it cannot loosen or flap, and follow the boat and engine manufacturer's transport instructions.

What makes the Oxford Fabric material a good choice?

Oxford Fabric with a PVC coating provides a durable outer layer for general storage protection. It helps reduce exposure to water, sunlight, weather, dust, and surface scratches. It is not a substitute for proper engine storage, ventilation, or manufacturer-recommended maintenance.

How should I clean and maintain this motor cover?

Clean the cover with cool or lukewarm water and a soft brush or cloth. Avoid harsh chemical detergents and abrasive tools that may damage the PVC coating. Allow the cover to air dry completely before folding and storing it.

When should I replace the outboard motor cover?

Replace the cover if it develops significant rips, tears, holes, seam failure, or brittleness. Damage can reduce its ability to protect the engine cowling from water, sunlight, dust, and scratches.

Is this an OEM cover?

No. This is an aftermarket outboard motor cover with a universal drawstring design. It is not presented as an OEM-manufactured component, and no specific OEM replacement number is confirmed for this product.

What are the shipping and return terms?

Shipping availability, delivery timing, and return eligibility depend on the order destination and the current store policy. Review the applicable options and policy details at checkout before completing your purchase.

Safety & Important Info
