How to Winterize Your Boat

Winter boat storage

If possible, place your boat in dry storage during the winter to prevent damage to your hull. A climate-controlled storage area is best. If you do choose dry storage, keep in mind your engine may be at risk during sudden hard freezes.

Remove the battery

Disconnect your boat’s battery and store it in a dry, climate-controlled location. Make sure your battery is fully charged when you store it and that you maintain the water level all winter.

Flush the engine with fresh water

Doing this will clear out any dirt, salt, and other substances that can corrode your engine. How you flush your engine will depend on the type of engine you have, so check your owner’s manual for the correct method.

Add fuel stabilizer

Fuel can break down and clog your engine if left sitting for too long. Fill your tank to about 95% capacity, then add a fuel stabilizer. Follow the directions in your owner’s manual or on the stabilizer’s packaging to add the correct amount.

Clean the hull

Start by checking your boat’s hull for cracks and gelcoat blisters. Cracks can be signs of a bigger problem and should be checked out by a professional. Drain the water from any blisters and seal them with an epoxy-based filler.

Scrape away any barnacles which have become attached to the hull of your boat, then pressure wash to remove additional scum and grime. This may be a good time to inspect your boat’s paint and take care of any touch ups it needs. After cleaning, treat the hull with a boat wax to protect the surface.

Clean the interior

If you plan to store your boat for several months, it’s a good idea to give the interior a thorough cleaning. Clean all vinyl, carpets, and surfaces to prevent the buildup of mold and mildew.

Keep your boat in good shape and you’ll be able to enjoy it for years to come. Contact Worldwide Auto Body for marine and recreational vehicle collision repair, paint, detailing, and more!
