Self-Storage Tips: Winterizing Your Boat

If you’re getting ready to put your boat away in a storage unit for the winter, it’s important to prepare it for storage first. Winterizing your boat will make sure you don’t have any problems starting it back up and getting the systems running when you put it back on the water. Today in the Affordable Family Storage blog, we’ll break down the essential steps of winterizing your boat before putting it in self-storage.

Take Care of Your Engine

The most important part of winterizing your boat is making sure the engine is ready for self-storage. There are a few things that you’ll need to do for your engine.

Flush Out Contaminants

Some boats have built-in hose attachments that you can use for this process. A built-in flushing system allows you to just attach your hose the motor and run the water. Letting it run for 10-15 minutes should be enough to get out any contaminants. If you don’t have a built-in system, you’ll need to get engine “ear muffs” which will allow you to attach a hose to your engine. You’ll have to run your engine in neutral during the flushing if you have to use the ear muffs.

Fog the Cylinders

It’s also a good idea to coat the inside of your engine with fogging oil. Fogging oil helps to prevent corrosion. Many boats let you just spray oil into the air intake to properly fog it, but it’s always a good idea to check your owner’s manual first to make sure you know the correct procedure.


Finally, you’ll want to flush your engine with antifreeze. If you don’t, water in the engine can freeze, expand, and cause damage. Check your boat’s manual on how to do this, as it will differ based on if you have an inboard or outboard motor.


Unless you’re using climate-controlled self-storage, the liquids in your boat are subject to freezing. Even if you do use climate-controlled self-storage, it’s still not the best idea to leave the liquids to just sit through the winter. Follow these tips for the different fuels and liquids in your boat.


Although your fuel won’t freeze, it can be ruined just sitting in your boat. If you use a fuel stabilizer, this won’t be a problem. You’ll want to run your engine after adding stabilizer so it can run its course through the fuel lines. If you’re close to empty, you could just drain the fuel tank instead.


You’ll want to change your oil before putting your boat in self-storage.


If you have a freshwater system, it’s recommended to drain your tanks and then put non-toxic antifreeze in.
