SRIMMIT Jetski Cover for 3-Seater PWCs 136-145in Black — 420D Waterproof, UV-Resistant

If you store, trailer, or dock a 3-seater personal watercraft, protecting its finish and interior is essential. This SRIMMIT jetski cover is built from thick 420D Oxford polyester with a six-layer nano coating to keep water out, reduce UV fading, and resist abrasion during regular highway towing. Designed to fit PWC lengths between 136 and 145 inches and widths up to 56 inches, the cover balances a secure, snug fit with ventilation to prevent trapped moisture.

How does this cover keep my jet ski dry during storms and transport?

The fabric offers 12,000mm water resistance and fully sealed seams to block heavy rain and snow. Four windproof buckles and a full elastic hem anchor the cover so it won’t lift at highway speeds, while reinforced stitching holds up under normal towing stresses.

• 420D Oxford with 6-layer nano coating for 12,000mm waterproof rating
• Double-needle seams plus sealed waterproof strips
• Four adjustable windproof buckles and elastic hem for a locked-in fit
• Includes flexible straps for extra security while trailering

Will this cover protect my hull and seat from sun, dirt, and scratches?

Yes—an SPF 85+ level of UV protection slows fading and surface degradation from sun exposure, and the smooth inner layer minimizes abrasion. It also blocks dust, bird droppings, leaves, and tree sap that can mar paint and upholstery.

• SPF 85+ UV protection shields gelcoat and upholstery
• Smooth inner lining reduces risk of scratches during use
• Repels dust, debris, and organic contaminants
• Regularly inspect coating after prolonged sun exposure for replacement timing

How does the cover manage moisture buildup and airflow?

Two vents—one on each side—promote airflow to prevent condensation and pooling from melt or humidity. The vents combined with the elastic hem reduce trapped moisture, keeping seats and hull surfaces drier during storage.

• Dual air vents allow moisture to escape
• Full elastic hem reduces flapping and water collection
• Tip rear or use a support pole if unusual hull shapes cause slight pooling
• Designed for standard handlebars; measure raised accessories before ordering

What size and care guidelines should I follow before buying?

The cover fits most three-seat PWCs from 136 to 145 inches long and up to 56 inches wide—measure overall length and hull width and leave 2–4 inches for ease of fitting. To preserve the nano coating, rinse with a hose or wipe with a damp cloth; do not machine wash and keep away from flames and hot engine surfaces.

• Fits 136–145 in length, up to 56 in width; compatible with Sea-Doo, Yamaha, Kawasaki, Honda, Polaris
• Allow 2–4 in extra room for installation; check raised handlebars or add-ons
• Hand clean only; avoid heaters, open flames, and cover hot engines
• Includes a compact storage bag for folding and off-season storage

Who is this for: This SRIMMIT heavy-duty jetski cover is intended for owners of three-seater PWCs who need reliable outdoor protection and secure trailering performance. It’s suited to boaters who tow regularly, store their craft outdoors, or want a long-lasting, UV-resistant barrier for Sea-Doo, Yamaha, Kawasaki, Honda, Polaris and similar models—provided you check measurements and avoid extreme high-speed towing or racing scenarios.
