Product Details

This heavy-duty waterproof Outboard Motor Cover helps protect an outboard motor from weather, UV exposure, dust, and other environmental hazards. It is designed for use with many Mercury, Yamaha, Honda, and other outboard motors in the 5–30 HP range. Because engine cowling shapes vary, always compare your motor's dimensions with the cover dimensions before ordering.

The cover is listed with Yamaha part number MAR-MTRCV-ER-10 as a reference. This is an aftermarket cover, not a Yamaha-branded OEM component; verify dimensions and shape for your specific motor.

  • Easy Installation: The slip-on design and drawstring closure allow the cover to be fitted and removed quickly.
  • Durable Material: Rugged Oxford fabric provides weather-resistant protection for routine storage and outdoor use.
  • UV Protection: Helps shield the motor cowling and finish from sun exposure and fading.

  • 1 × Outboard Motor Cover, 19.7 in × 11.8 in × 15.7 in

Installation Notes

  1. Make sure the outboard motor is cool, clean, and dry before installing the cover.
  2. Slide the cover over the motor from top to bottom, keeping the cover centered over the cowling.
  3. Pull the drawstring at the base until the cover is snug, then secure the drawstring so it does not loosen during storage.
  4. Do not force the cover over a motor that exceeds the listed dimensions or has an incompatible cowling shape.

Troubleshooting & FAQ

How do I confirm that this cover will fit my motor?

Measure the length, width, and height of your motor's cowling and compare the measurements with the cover size of 19.7 in × 11.8 in × 15.7 in. Also compare the cowling shape and the position of any controls or protruding parts. The 5–30 HP range is a general application guide and does not replace dimensional verification.

Is this an OEM Yamaha cover?

No. This listing is for an aftermarket outboard motor cover. Yamaha part number MAR-MTRCV-ER-10 is provided as a reference for comparison, but the cover is not represented as a Yamaha-branded OEM component.

Can I trailer my boat with this cover installed?

High-speed trailering with a simple drawstring cover is not recommended. Wind may cause the cover to billow, loosen, or become damaged. Remove the cover before trailering unless it is specifically secured and approved for transport use.

What is Oxford fabric?

Oxford fabric is a woven material commonly used for protective covers. It provides a balance of flexibility, abrasion resistance, and weather resistance. Actual protection depends on correct installation and storage conditions.

How should I clean and store the cover?

Clean the cover with a soft brush, mild soap, and lukewarm water. Rinse thoroughly and allow it to air-dry completely before folding or reinstalling it. Avoid bleach, harsh chemicals, abrasive brushes, and machine drying, which may damage the fabric or its coating.

Does the package include anything besides the cover?

The package includes one outboard motor cover. No motor parts, mounting hardware, or additional accessories are included unless specifically stated in the order details.

Shipping speed and cost

Available shipping methods, delivery estimates, and shipping charges are shown at checkout and may vary by destination.

Warranty and returns

Warranty coverage and return eligibility are governed by the applicable store policy. Contact customer support with your order details if the item arrives damaged or has a manufacturing issue.
