Winterizing Your Jet Ski and Recreational Water Vehicles: Protect Your Investment

​Don’t let winter damage your Jet Ski or boat.

​Learn the essential steps to winterize your recreational water vehicles and why proper storage matters for insurance protection.

---

Summer fun on the water eventually comes to an end—but your responsibility to care for your Jet Ski, boat, or other recreational watercraft doesn’t stop when the season does. Without proper winterization, cold weather, freezing temperatures, and long storage periods can cause costly damage. Even worse, some insurance claims may be denied if neglect is found to be the cause.
Here’s why winterizing matters and how to do it right.

1. Why Winterizing Is So Important
Watercraft engines and systems aren’t built to handle freezing temperatures without preparation. Left unprotected, you could face:

• Cracked engine blocks or exhaust manifolds from frozen water inside
• Fuel system breakdowns caused by untreated gasoline
• Battery failure after months of sitting idle
• Mold, mildew, and hull damage from poor storage conditions

💡 Tip: Repairing freeze damage often costs far more than the effort it takes to properly winterize.

2. Steps to Winterize a Jet Ski or Boat
While specific steps vary by vehicle type, here are the basics most owners should follow:

• Drain all water from the engine, exhaust, and cooling system.
• Stabilize the fuel with a marine fuel stabilizer to prevent clogging and breakdown.
• Fog the engine (spray oil inside cylinders) to protect against corrosion.
• Disconnect or remove the battery and store it in a cool, dry place.
• Clean and dry the hull/interior to prevent mold, mildew, and staining.
• Use a proper cover to keep dust, debris, and pests out during storage.

3. Storage Options: Garage, Storage Facility, or Dock?

• Indoor storage: Best protection from freezing temps and moisture.
• Covered outdoor storage: Works with a high-quality, weatherproof cover.
• Dock storage: Riskier in cold climates unless you use de-icers and heavy-duty covers.

Choose based on your local climate, space, and budget.

4. Insurance Considerations
Many owners assume their watercraft is fully covered while in storage. But keep in mind:

• Damage from lack of maintenance or winterization may not be covered.
• Theft and fire risks remain during off-season—comprehensive coverage is key.
• Some carriers may even ask for proof of proper storage after a claim.

💡 Tip: Ask your agent if your policy covers year-round risks, not just on-water use.

Final Thoughts
Winterizing your Jet Ski or boat is one of the smartest ways to protect your investment. With just a little preparation, you’ll save yourself from expensive repairs, keep your insurance coverage valid, and ensure your watercraft is ready for fun as soon as warm weather returns.
