Winter storage is a critical part of boat ownership. Improper storage can lead to costly damage, while proper preparation ensures that your boat and outboard engine will be ready to go when warm weather returns. Whether you're new to boating or looking for a refresher, follow these essential steps to protect your investment.
1. Clean and Inspect Your Boat
Before storing your boat, thoroughly clean both the interior and exterior. Remove dirt, salt, and grime to prevent corrosion and mold growth. Check the hull for any damage, and make necessary repairs before storage to avoid worsening issues over time.
2. Drain and Stabilize the Fuel System
Leaving fuel in the tank for months can lead to degradation and moisture buildup, which can damage the engine. Follow these steps to protect your fuel system:
-
Fill the tank to about 95% full to minimize condensation.
-
Add a marine-grade fuel stabilizer and run the engine for several minutes to distribute it throughout the system.
-
If possible, drain the fuel system (VST/carburetor) and fuel lines to prevent varnish buildup over the cold winter months.
3. Protect the Engine
-
Flush the cooling system with fresh water to remove salt and debris.
-
If your engine is water-cooled, drain any remaining water to prevent freezing and cracking.
-
Apply fogging oil to the cylinders to protect against corrosion.
-
Change the engine oil and replace the oil filter to remove contaminants.
-
Store outboard engines in the "down" position to allow excess water or moisture to drain out of the water systems.
4. Remove and Store the Battery
Cold temperatures can drain your battery. To prolong its lifespan:
-
Disconnect the battery and store it in a cool, dry place.
-
Keep it on a trickle charger or charge it periodically to maintain its health.
5. Lubricate Moving Parts
Apply marine grease to steering mechanisms, throttle cables, and other moving components to prevent rust and stiffness.
6. Cover and Store Your Boat Properly
A high-quality, breathable boat cover is essential to protect against dirt, moisture, and pests. If possible, store your boat in a dry, covered area such as a garage or storage facility. If outdoor storage is your only option:
-
Use a sturdy cover with ventilation to prevent mold buildup.
-
Place the boat on a trailer or blocks to keep it off the ground.
-
Tilt the boat slightly to allow water runoff.
7. Check on Your Boat Periodically
Throughout the winter, check on your boat to ensure no moisture or pest issues arise. Remove any accumulated snow or rainwater from the cover to prevent excess weight and damage.
By following these steps, you'll ensure that your boat and outboard engine remain in excellent condition throughout the winter. Proper storage minimizes the risk of costly repairs and helps you get back on the water with confidence when the boating season returns.
