The Basics of Boat Winterization

Last updated 5 years ago

Winter is nearly here, so it’s almost time to let your boat rest for the season. But before you pull the cover over it, make sure to follow proper winterization procedures to keep your boat safe from the elements while you’re not using it. Even if you plan to have your boat spend the winter at an indoor storage facility, you still need to protect it from condensation and freezing temperatures. Follow these steps to make sure your boat stays in peak condition for next spring:

Wash the Hull

Mud and grime are enemies of your boat’s paint. Also, any stress fractures in the boat’s hull can remain invisible under a layer of dirt. Thoroughly spray your boat down with a power washer, and check for cracks. If you see any, have them repaired now or you’ll face delays in the busy spring season.

Stabilize the Fuel Line

As the temperature goes down in the wintertime, your boat’s fuel line becomes susceptible to freezing, which can cause cracks. Also, some of the chemical compounds in the gasoline will evaporate, leaving behind heavier, stickier fluids that can clog the system. Add stabilizer to the gas tank, and then let the engine idle for about 15 minutes to make sure the stabilizer gets distributed throughout the system. 

Winterize the Engine

To protect the engine against condensation and rust, you will need to drain the oil, flush it, and then add new, lighter-grade winter oil. Add antifreeze as instructed by your owner’s manual. You should also spray moisture repellent on any wires connected to electrical equipment. Remove the battery last.

Cover and Store

After you have completed all the items on your boat winterization checklist, you will be ready to cover and store your boat for the winter. If you’ve done everything properly, you can look forward to a full season of problem-free boating next year.
