SRIMMIT Heavy Duty Jetski Cover for 3-Seater 136–145 in — Waterproof, UV-Resistant Black

SRIMMIT's Heavy Duty Jetski Cover for 3-seaters (136–145 in) is a waterproof, UV-resistant PWC cover built to protect your craft from rain, sun, dust, and road travel.

Designed for owners of Sea-Doo, Yamaha, Kawasaki, Honda, Polaris and similar three-seat personal watercraft, this cover combines a thick 420D Oxford fabric with a 6-layer nano coating to block water and sunlight while remaining gentle on gelcoat and upholstery. Reinforced seams, multiple fasteners and ventilation keep the cover secure and reduce moisture buildup during seasonal storage or highway towing.

How does this cover defend my jetski against the elements?

The shell uses a nano-coated 420D polyester that resists heavy rain and sunlight without abrasive backing that could scratch finishes. Sealed seam strips and double-needle stitching increase waterproofing, while SPF 85+ protection limits UV fading of seats and hull over time.

• 12000mm waterproof rating from a 6-layer interior coating
• Double-needle seams plus sealed strips for reliable water resistance
• SPF 85+ UV protection to reduce color fading and material breakdown

Will this cover stay put in wind or while I trailer my PWC?

Yes — the cover is made to stay secure during normal highway speeds and in gusty conditions thanks to multiple buckles, straps and a full elastic hem. It’s tested for common trailer wind pressures, and extra retention points minimize lift and flapping.

• Four adjustable elastic windproof buckles at front, middle and rear
• Full elastic hem that hugs the hull to reduce wind intrusion
• Four flexible straps for added attachment when towing

How does the cover prevent moisture buildup and inside condensation?

Two side air vents allow airflow to escape, which helps prevent trapped moisture from pooling on seats or decks. The smooth inner layer avoids scratching, and the vents reduce the risk of mildew compared with fully sealed covers.

• Dual air vents keep air circulating inside the cover
• Smooth inner nano-coated layer protects finish while allowing water runoff
• Elastic hem and recommended tilt/support options reduce water pooling

Will this fit my 3-seat jetski and how do I care for it?

The SRIMMIT cover fits most three-seat PWCs between 136 and 145 inches long and up to 56 inches wide; measure length and overall height (including accessories) before ordering. Cleaning is simple: rinse or wipe with a damp cloth; avoid machine washing to preserve the nano coating.

• Recommended fit range: 136–145 in length, up to 56 in width
• Leave 2–4 in extra length for easier installation and removal
• Hand rinse or wipe only; do not machine wash to protect coating

Who is this for? This heavy-duty cover suits PWC owners who need durable outdoor protection and frequent trailering capability — ideal for seasonal storage, daily dock use, and weekend transport. It’s best for standard-handlebar three-seater models without large aftermarket towers or oversized accessories; if you have raised handlebars, mirrors, or a rear platform, measure overall height before purchasing. Keep the cover away from flames and allow engines to cool before covering to protect the fabric and coating.
