Setup and Installation
Proper installation of your SBU Jet Ski Cover is crucial for maximum protection and longevity. Follow these steps for a secure fit:
- Prepare the Watercraft: Ensure your jet ski is clean and dry before covering. Remove any sharp objects or accessories that could snag or tear the cover.
- Unfold the Cover: Lay the cover out flat, identifying the front (bow) and rear (stern) sections. The front typically has a designated opening for the trailer hitch.
- Position the Cover: Start from the front of the jet ski. Carefully pull the cover over the bow, aligning the trailer hitch opening if applicable.
- Work Towards the Rear: Gradually pull the cover over the entire personal watercraft, ensuring it drapes evenly over all surfaces. The elastic hem around the bottom will help provide a snug fit.
- Secure Straps: Locate the detachable side-release strap buckles. Pass the straps under the jet ski and connect them, tightening them securely to prevent the cover from flapping in the wind, especially during trailering. Ensure straps are not twisted.
- Check Air Vents: Verify that the rear air vents are unobstructed to allow for proper air circulation and reduce wind lofting.
- Utilize Fuel Tank Access: If needed, use the integrated fuel tank access doors for convenient refueling.

Maintenance
To ensure the longevity and effectiveness of your SBU Jet Ski Cover, follow these maintenance guidelines:
- Regular Cleaning: Periodically clean the cover with mild soap and water. Use a soft brush or sponge to remove dirt, grime, and mildew. Rinse thoroughly and allow to air dry completely before folding and storing.
- Avoid Harsh Chemicals: Do not use bleach, harsh detergents, or abrasive cleaners, as these can damage the fabric and its water-resistant coating.
- Inspect for Damage: Regularly check the cover for any signs of wear, tears, or damage to seams and straps. Promptly repair any minor damage to prevent it from worsening.
- Proper Storage: When not in use, fold the dry cover neatly and store it in the attached storage bag in a cool, dry place away from direct sunlight and extreme temperatures.
- Winter Storage: The cover can serve as an alternative to shrink wrap for winter storage. Ensure the jet ski is clean and dry, and the cover is securely fastened to protect against temperature extremes.

- Cover Does Not Fit Snugly:
- Ensure the cover is correctly oriented (front to back).
