Troubleshooting & FAQ

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

This cover offers a universal fit for most 150 HP to 225 HP 4-stroke outboard motors from Mercury, Yamaha, and Honda. To ensure a proper fit, compare your engine's horsepower and dimensions with the specifications provided: 97.64" × 77.56" (248 × 197 cm).

Can I use this cover while trailering my boat?

This cover is designed for stationary protection, such as during mooring or storage. It is not recommended for use while trailering at high speeds, as wind can cause excessive stress on the fabric and seams.

How should I clean and maintain the cover?

To clean the cover, use a soft brush and mild soap with lukewarm water. Rinse thoroughly and allow it to air dry completely before folding and storing. Avoid using harsh chemical cleaners, as they may damage the waterproof PVC coating.

Will this cover fit a 2-stroke engine?

This cover is tailored for the dimensions and shape of modern 4-stroke outboards. While it might fit over some 2-stroke engines in the same HP range, the fit may not be as precise. We recommend measuring your engine and comparing it to the cover's dimensions.
