As Ontario’s lakes freeze over and the summer season winds down, jet ski enthusiasts face an important question: What’s the best way to store and maintain a jet ski during the winter months?
Proper winter storage and maintenance not only extend the life of your watercraft but also ensure it’s ready to hit the waves the moment warm weather returns. Even if you rely on jet ski rental in Toronto and Lake Simcoe during the summer, understanding how off-season care works can give you peace of mind — especially if you plan to own one in the future.
Here’s your guide to winterizing and maintaining a jet ski through the off-season.
❄️ Step 1: Thorough Cleaning
Before storing your jet ski, give it a deep clean.
-
Flush the engine with fresh water to remove salt, algae, and debris.
-
Wash the hull with soap and water, then dry it completely to prevent mold or mildew.
-
Wax the exterior to protect the finish against dust and temperature changes.
A spotless watercraft is less likely to suffer from corrosion or hidden damage during storage.
🛠 Step 2: Engine & Fuel System Prep
-
Stabilize the fuel: Add a fuel stabilizer and run the engine briefly to distribute it through the system. This prevents fuel breakdown and clogging.
-
Fog the engine: Spray fogging oil into the cylinders to protect against rust.
-
Drain excess water: Tilt the jet ski slightly to remove leftover water in the exhaust and cooling system.
🔋 Step 3: Battery Care
The cold can drain batteries quickly.
-
Disconnect and remove the battery.
-
Store it in a dry, room-temperature environment.
-
Attach it to a trickle charger every few weeks to keep it healthy.
This simple step saves you from buying a new battery when spring arrives.
🛡 Step 4: Cover & Storage Location
-
Use a high-quality, fitted cover to protect against dust, pests, and moisture.
-
Choose indoor storage if possible (garage or storage facility).
-
If storing outdoors, elevate your jet ski off the ground and cover it securely to guard against snow and ice.
🔧 Step 5: Off-Season Maintenance Checks
Winter is the perfect time to schedule maintenance that often gets overlooked during the busy riding season:
-
Inspect the hull for scratches or cracks.
-
Check the impeller and pump for wear.
-
Replace spark plugs if needed.
-
Review owner’s manual for manufacturer-specific winterization tips.
🌊 Why This Matters (Even for Renters)

Reputable rental companies perform these steps every off-season to keep their fleets in top condition.

✅ Final Thoughts
Winterizing a jet ski may seem like extra effort, but it pays off with longer-lasting equipment and smoother rides when the season returns. From stabilizing fuel to protecting the hull, each step ensures your investment is well cared for.
