Installation Notes

Ensure the engine is off and cool to the touch before installation.
Tilt the outboard motor up to a convenient position.
Unfold the cover and identify the top and front. Slip it over the cowling from top to bottom.
Once the cover is fully on, close the heavy-duty zipper to secure it around the motor shaft.
Fasten the buckle strap snugly to prevent the cover from shifting.
Pull the drawstring at the bottom hem to cinch the cover tightly against the lower unit. This completes the triple-lock system.
Tuck away any excess strap or drawstring to prevent flapping during trailering.

Troubleshooting & FAQ

How do I ensure this universal cover fits my 100-150 HP motor?

This cover is designed for a universal fit based on engine horsepower and general dimensions. Always check your motor's circumference and height against the cover's dimensions (89" C × 74.8" H) to confirm a good fit, as engine housing sizes can vary between manufacturers and models.

Can I use this cover while trailering my boat?

Yes, the triple-locking system (zipper, buckle, and drawstring) is designed to keep the cover secure during trailering at highway speeds. Ensure all three locking mechanisms are fastened tightly.

What is the triple-locking system?

It is a three-part security system for a snug fit. It includes a heavy-duty zipper for easy installation, a quick-release buckle strap to prevent billowing, and a drawstring hem to cinch the bottom opening tightly.

How do I clean and maintain the cover?

Clean the cover with cool water and a soft brush. Avoid harsh detergents or bleach, which can damage the waterproof coating. Allow it to air dry completely before folding and storing it in the provided bag.

Is this cover fully waterproof?

The 600D marine-grade polyester fabric has a waterproof coating that repels water effectively, protecting your engine from rain, snow, and moisture during storage. However, seams are not typically tape-sealed, so it is considered highly water-resistant rather than fully submersible.

What should I do if the cover feels too loose or too tight?

If the cover is loose, use the buckle and drawstring to create a tighter fit. If it seems too tight to install, double-check your motor's measurements against the product dimensions (89" C × 74.8" H) to ensure you have the correct size.
