Troubleshooting & FAQ
How do I confirm this cover will fit my specific motor?
This is a universal cover designed for most outboard motors in the 5-30 HP range. The most reliable way to confirm fit is to measure your motor's dimensions and compare them to this cover's size: 19.7" Length x 11.8" Width x 15.7" Height. As long as your motor is within these dimensions, the cover should fit well.
Can I trailer my boat with this cover on the motor?
It is generally not recommended to trailer a boat at high speeds with a simple drawstring cover installed. Wind can cause the cover to billow, rip, or fly off, potentially damaging the cover or the motor's finish. For trailering, consider a heavy-duty, strap-secured cover designed for transport.
What is "Oxford Fabric" and what does the "D" rating mean?
Oxford fabric is a durable, woven material known for its water-resistant and wear-resistant properties. The "D" stands for Denier, a measurement of a fiber's thickness and weight. A higher denier number, like 600D, indicates a thicker, stronger, and more heavy-duty fabric compared to a lower number like 210D.
How should I clean and care for this cover?
To clean the cover, use a soft brush with mild soap and lukewarm water. Rinse it thoroughly and let it air dry completely before storing or reinstalling it on the motor. Avoid using harsh chemical detergents or bleach, as they can damage the waterproof coating and fabric.
