Prepping Your Boat for Winter: A Step-By-Step Guide to Winterizing for Self Storage

Prepping Your Boat for Winter

Your boat is a huge investment, and you’ll want to keep it properly protected for the winter months. If you don’t have the appropriate space to store your boat on your property, a self storage facility is the ideal option. Trusted Self Storage has a variety of locations that offer secure storage for your boat. When choosing a facility, be sure to check for any special requirements they may have for storing boats.

When storing your boat in a self-storage facility, be sure to cover the boat with a tarp or other protective cover. This will safeguard your boat from the elements and keep it in top condition. Additionally, you should consider using a dehumidifier in an indoor storage space to help keep the air dry and prevent any moisture from accumulating.

Winterizing your boat is essential for protecting your investment and keeping it in good condition for the following season. However, it can seem overwhelming to take on this task. This step-by-step guide will provide you with the necessary information to effectively prepare your boat for a safe self-storage period.

Prepping Your Boat For Winter

Step 1 – Check for Damage

The first step in prepping your boat for winter is to inspect it for any damage that may have occurred over the boating season. This includes inspecting the hull, deck, and any other parts of the boat that may have been affected by wear and tear.

You should also check for any signs of corrosion, as well as any cracks or holes in the hull. This includes checking for cracks or worn spots in the decking, as well as any loose screws or bolts. Additionally, check the boat’s railings to make sure they are securely attached to the boat.

Finally, inspect the engine and any other mechanical parts of the boat. Check for any signs of wear and tear, as well as any signs of corrosion. Additionally, check the engine oil and other fluids to make sure they are at the right levels.

If you notice any damage or other issues, it’s best to have all of them repaired prior to storing the boat.

Step 2 – Drain the Water from the Engine

The next step in prepping your boat for winter is to drain the water from the engine. This is essential for preventing corrosion and other damage. To do this, you will need to locate the drain plug on the engine and remove it. Once the plug is removed, water will start to drain from the engine. Don’t forget to disconnect the hose from the water intake and drain the water from the hose.

Once the water has drained from the engine, it’s important to replace the drain plug and tighten it securely. Additionally, you should reconnect the water intake hose and make sure it is securely attached. This will help prevent any leaks from occurring while the boat is stored.

Step 3 – Cleaning and Waxing the Hull

Cleaning and waxing the hull will help protect the exterior of your boat from the elements and keep it looking nice for the following season. Use mild soap and warm water. For tougher stains, you may need to use a stronger cleaner. Be sure to give it a thorough rinse after cleaning.

Once the hull is clean, you can then apply a coat of wax. When applying the wax, be sure to use a soft cloth or sponge and work in small circles. Once the wax is applied, allow it to dry before you store your boat.

Step 4 – Winterizing the Electrical System

Now you’re ready to winterize the electrical system to protect against moisture and corrosion. To do this, you will need to disconnect the battery from the boat and store it in a cool, dry place. Additionally, you should disconnect any other electrical components and store them in a safe place.

Once the battery and other electrical components are disconnected, you should check the wiring for any signs of wear and tear. If you notice any issues, get them repaired before you store the boat. Additionally, it’s a good idea to lubricate any moving parts on the electrical components. This will help them move more freely.

Step 5 – Treating Your Boat’s Fuel System

Your next task is to treat the fuel system. To do this, you will need to drain the fuel tank and add a fuel stabilizer. This keeps the fuel fresh and prevents it from deteriorating over the winter.
Once the fuel tank is drained, you should also change the spark plugs and oil filters. This will help ensure that your engine is running smoothly when you take the boat out in the spring. Don’t forget to check the fuel lines for any signs of wear or damage.

Step 6 – Cleaning the Boat’s Interior

The final step in getting your boat ready for winter is to tidy the interior of the boat. This includes cleaning out any debris, vacuuming the floors, and wiping down any surfaces. Additionally, you should check for any signs of mold or mildew and treat them accordingly.

Once the interior is clean and dry, you should also make sure all of the windows are securely shut. This will help prevent any excess moisture from entering the boat. Cover any furniture or other items in the boat with a tarp or plastic sheeting to protect them from the elements.


Prepping your boat for winter is essential for protecting your investment and keeping it in good condition. With this step-by-step guide, you can ensure that your boat is properly winterized for safe self-storage.
