Top 10 Winter Storage Tips for Your Boat

September 4, 2026

The end of boating season is always a little depressing.

One weekend you're running across the lake with the throttle down, and the next you're standing in the driveway staring at your boat under a cover thinking, "Didn't I just put this thing in the water?"

But how you put your boat away can have a big impact on what happens when you turn the key next spring.

Here are my Top 10 Winter Storage Tips for Your Boat.

1. Don't Just Park It

Winterizing isn't simply putting the cover on and walking away. Follow your boat and engine manufacturer's recommended storage procedures.

2. Change the Engine Oil

Old oil can contain moisture and contaminants. If your manufacturer recommends changing it before storage, get it done.

3. Protect the Fuel System

Gasoline sitting for months can create problems. Follow manufacturer recommendations regarding fuel stabilizer, tank levels and fuel-system preparation.

4. Check the Lower-Unit Lubricant

Inspect and service the gearcase as recommended. Water in the lower unit can become a very unpleasant spring surprise.

5. Protect the Cooling System

Freezing temperatures and trapped water don't play well together. Properly drain or winterize systems according to manufacturer specifications.

6. Take Care of Your Batteries

Disconnect, remove or maintain batteries as appropriate. There's nothing exciting about arriving for your first spring trip with a dead battery.

7. Clean the Boat

Wash it. Clean the interior. Remove food, trash, wet towels and fishing gear.

Trust me—the mice don't need snacks.

8. Get Everything Dry

Moisture means mildew, corrosion and funky smells. Make sure compartments, bilges and storage areas are clean and dry.

9. Cover It Properly

Use a quality, well-supported cover that keeps weather out while allowing appropriate ventilation. Snow and standing water can put tremendous weight on a poorly supported cover.

10. Inspect Before You Store

Look for leaks, damaged hoses, loose connections, worn belts, propeller damage and anything else that needs attention.

Fixing a small problem now can prevent a bigger problem later.

And here's one final Outdoor Man rule:

Maintenance and protection go together.

A Marine Service Contract can help protect against certain unexpected covered mechanical failures, but it isn't a replacement for proper maintenance. In fact, keeping good maintenance records can be extremely important if you ever have a claim.

Winterize it correctly. Maintain it correctly. Protect it correctly.

Because when that first warm Saturday arrives next spring, there's only one thing you want to hear:

VROOM.

Not click...click...click.

Take care of your boat now so you can spend next season doing what you bought it for.

Getting out on the water.
