How to De-Winterize Your Boat After Boat Storage

It’s almost time for boating season again, which means boat owners are preparing to get their boats out of winter storage and ready for the de-winterization process.

If you’re new to the boating world and not sure what the de-winterization process is, don’t worry. It’s general maintenance that is done every spring before boats hit the water yet again. To learn more about this process, keep reading below. 


De-Winterization Process

The de-winterization process for boats is fairly simple. It takes just a few hours of your time and then your boat will be ready to hit the water. Here’s what is typically done during the de-winterization process:

Check the battery

It’s important to check the battery during the de-winterization process. This is because batteries that go unused for long periods of time, or that sit in cooler temps, may be more likely to drain. Therefore, checking them and making sure they’re fully charged and operational is incredibly important. 

1. Test the electronics

Once the battery has been checked, it’s important to test the electronics on board. This includes running lights, the radio, etc. Mechanical issues are more likely to come up after a boat is in storage for several months, so you need to make sure everything is in working order before taking your boat out on the water. 

2. Change the oil

Next, the oil should be changed in the engine. Just like a car, this step is important to make sure the boat engine is operating at its optimal level before you enter a new boating season.

3. Inspect the gas tank and fuel lines

Once the oil is changed, you need to also inspect the gas tank and fuel lines for any damage or leaking. While the chances are slim, this does sometimes happen during boat storage and you’ll want to have everything repaired before putting the boat in the water.

4. Inspect the interior and exterior

Lastly, make sure to inspect the entire boat, inside and out. Look for damage like scratches and dents, upholstery tears, stains, etc. While your boat should be covered in boat storage, sometimes moisture can leak inside and cause damage to materials. The transport of boats in and out of storage can also cause some exterior damage. Therefore,  take some time to look your boat over at length and confirm everything looks the same as it did before you stored it.
