How to winterize your jet ski for storage
Clean and protect the exterior
Start by thoroughly washing, waxing, and buffing your jet ski to protect the paint. Then, remove all items from the storage compartments and leave them slightly open for airflow. Use a breathable cover to prevent moisture buildup, which can lead to mold or mildew.
Engine and fuel system
Run the engine to operating temperature, then add a fuel stabilizer or drain the fuel system completely. Also drain the engine and exhaust system to remove any remaining water or fuel. Finally, change the oil and oil filter to ensure your engine stays in top condition during storage.
Cooling system
Flush the cooling system with fresh water to remove salt, sand, and debris. If you live in a freezing climate, mix water and RV antifreeze to flush the system and prevent damage from ice formation.
Battery care
Remove the battery and store it in a cool, dry place. Use a battery tender to maintain its charge throughout the storage period.
Trailer prep (if applicable)
If you have a trailer for your jet ski, check the tire pressure and bearings. Use wheel chocks to prevent rolling, and apply grease to all moving parts to keep them in good working order.
Jet ski storage options
Knowing how to store your jet ski, whether at home, in a self storage unit, or at a marina, extends the life of your watercraft and keeps it ready for your next adventure.
Home-based storage
Best for: Convenience, low cost, and short-term needs
Home storage is ideal if you want quick access and want to avoid monthly fees.
Your garage is a great choice, as it offers security and protection from the elements, though it can take up significant space. For example, if your jet ski has a double trailer, make sure it fits before committing. There is a way you can maximize space in your garage though: a portable jet ski dolly, which lets you switch things up when needed.
Another accessible option is just storing them in your backyard, but that requires a high-quality cover to protect it from the elements.
If you have a shed, it can provide some weather protection and added security, but check for size restrictions or HOA rules before storing.
In all three cases, you should winterize your jet ski and implement security measures like locks or alarms. For better protection, try tilting the jet ski back, removing drain plugs, or using a lift to keep it off the ground.
Key consideration: Always check local HOA rules and ensure your storage method protects against weather, theft, and pests.
Self storage facilities
Best for: Long-term, secure, and space-saving storage.
Self storage facilities offer many options for different needs and budgets.
Indoor or climate-controlled units(opens in new tab) are safest against weather, theft and corrosion, so they’re ideal for valuable jet skis or harsh climates. However, they come at a higher cost.
Drive-up units(opens in new tab) make loading and unloading easy, but may lack climate control, so they’re perfect for frequent users or those with trailers.
Covered outdoor units are a more affordable option, and they do offer some weather protection but less security. They’re suitable for short-term storage or if you’re on a budget.
Outdoor uncovered units are the cheapest, but provide minimal protection: best for short-term storage if you use a high-quality cover and locks.
Size guide: A 10’x10’(opens in new tab) unit fits compact jet skis only, a 10’x15’(opens in new tab) unit accommodates a large jet ski or two smaller ones with gear, and a 10’x20’(opens in new tab) unit is perfect for multiple jet skis, workshop space, or a boat and jet ski combo.
For more information, you can consult our storage unit size guide(opens in new tab) and size calculator(opens in new tab). If your jet ski is on the larger side, our boat storage guide can also be helpful. Regarding costs, we have updated information on storage unit prices(opens in new tab), too.
Amenities to look for: Prioritize self storage amenities(opens in new tab) such as 24/7 access, surveillance cameras, electrical outlets (for battery tenders), wash stations, and drive-up access.
Marina and dry-stack waterfront storage
Best for: Convenience, proximity to water, and added services
If you want to keep your jet ski close to the water, marina and waterfront storage is a great choice. Dry stack storage eliminates the need for trailering and often includes services like fueling, cleaning, and maintenance. However, it can be expensive and may require advance booking.
Floating docks provide easy access and no trailering, but they are costly and offer limited weather protection, making them ideal for waterfront homeowners. Jet ski lifts protect your jet ski from water damage and provide a stable platform, but they come with a high upfront cost and complex installation, so they’re best for long-term, permanent storage.
Cost: Typically the most expensive option, but offers unmatched convenience for frequent riders.
Dealership and boat storage lots
Best for: professional care and winterization services
Dealership storage often includes winterization and de-winterization services, but availability is limited and costs are higher. Check with local dealerships for package options.
Boat storage lots are secure and often located near ramps, but are usually uncovered. Use a trailer lock for added security.
Peer-to-peer storage
Best for: affordable, flexible, and local options
Platforms like Neighbor connect you with local hosts offering unused space such as garages, driveways, or barns. This option is often cheaper than commercial storage, but always verify security and insurance before committing.
Final checklist before storing
Once you’ve decided which way you’ll go in storing your jet ski, let’s recap on the steps you ought to follow:
- Clean, wax, and cover your jet ski.
- Drain fuel and water, stabilize fuel, and change the oil.
- Remove and store the battery with a tender.
- Flush the cooling system.
- Check trailer tires, bearings, and locks.
- Choose the right storage option for your climate and budget.

The Art of Maximalist Decor: More of What You Love, None of the Chaos
Maximalism decor is the design philosophy that more is more — and then some. What is maximalism, exactly? It’s the belief that every object earns its place not because it fits a neutral palette, but because it means something to the person who brought it home. Your shelves might hold dog-eared fantasy novels from high school, a ceramic frog rescued from a flea market and the postcard your best friend mailed from the other side of the world. None of those objects belong to the same collection. And yet, somehow, they still belong together.

Their screens are thin, their internal components are delicate, and they’re designed to sit still on a stand, not ride in the back of a moving truck.
