Product Details

It is intended for use with many Mercury, Yamaha, and Honda outboards; always compare your engine’s dimensions and shape with the cover dimensions before ordering.

Installation Notes

  1. Turn off the engine and allow it to cool completely before installing the cover.
  2. Clean and dry the outboard motor to avoid trapping moisture or debris beneath the cover.

  4. Carefully slip the cover over the engine cowling from top to bottom.
  5. Adjust the cover so it rests smoothly over the engine without excessive bunching.
  6. Use the zipper to close the cover around the lower portion of the motor as designed.
  7. Tighten the drawstring at the base for a snug fit.
  8. Confirm that the cover is secure and that the cowling is fully covered before leaving the boat unattended.

Troubleshooting & FAQ

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

The cover is intended for many 150–225 HP outboard motors, including applications from Mercury, Yamaha, and Honda. Compatibility is not determined by horsepower alone. Compare your engine’s overall cowling shape and dimensions with the listed cover dimensions of 97.64 × 77.56 inches (248 × 197 cm) before ordering.

Can I use this cover while trailering my boat?

This cover is intended for stationary protection during mooring or storage. It is not recommended for high-speed trailering because wind pressure may place excessive stress on the fabric, zipper, and seams.

How should I clean and maintain the cover?

Use a soft brush and mild soap with lukewarm water. Rinse thoroughly and allow the cover to air dry completely before folding and storing it. Avoid harsh chemical cleaners that could damage the PVC coating.

Will this cover fit a 2-stroke engine?

Fit depends on the engine’s cowling dimensions and shape rather than horsepower alone. The cover is described for many modern outboards, but a specific 2-stroke application has not been confirmed. Measure your engine and compare it with the cover dimensions before purchase.

Is this an OEM cover?

No. This listing is for an aftermarket outboard motor cover. It is not an original equipment manufacturer cover.

How should the cover be stored?

Remove the cover periodically to inspect the engine and allow ventilation. Before storage, clean the cover, let it dry completely, fold it loosely, and keep it in a dry location away from sharp objects and prolonged direct sunlight.

Safety & Important Info

  • Confirm the cover dimensions, cowling shape, and engine clearance before ordering.
  • Install the cover only when the engine is switched off and completely cool.
  • Do not use the cover as a substitute for proper engine maintenance or winterization.
  • Do not use it for high-speed trailering unless the manufacturer specifically approves that application.
  • This is an aftermarket cover, not an OEM component.
