Troubleshooting & FAQ
How do I know if this cover will fit my specific motor?
This cover is designed for universal fit on most 60-100 HP 4-stroke outboards from Mercury, Yamaha, and Honda. The best way to ensure fit is to compare the cover's dimensions (78.74" × 66.93") with your motor's measurements. If your motor is within these dimensions, the cover should fit well.
Can this cover be used while the engine is running or during trailering?
No, this cover is designed for storage purposes only. It must be removed before starting the engine or trailering your boat to prevent damage to the cover, engine, and to avoid safety hazards.
How do I clean the cover?
Clean the cover with a soft brush and lukewarm water. Avoid using harsh chemical detergents, which can damage the PVC coating and fabric. Allow it to air dry completely before folding and storing it in the provided bag.
What makes this cover different from an OEM branded cover?
Our aftermarket cover is engineered to meet or exceed OEM specifications for fit and material quality but is offered at a more competitive price. It provides comparable protection from water, UV, and scratches without the OEM branding.
Is the material truly 100% waterproof?
Yes, the 600D Oxford fabric has an inner PVC coating and double-stitched seams, which prevent water from penetrating, keeping your engine dry even in heavy rain.
What are the signs that I need to replace my motor cover?
Look for signs of material degradation such as cracking, thinning, significant fading, or any tears and rips. If the cover is no longer fitting snugly or its waterproof properties are compromised, it's time for a replacement to ensure your engine remains protected.
