What temperature do you need to winterize your boat?

As soon as the weather gets below 32 degrees, water begins to freeze, with water with impurities or saltwater in it starting to freeze at 28 degrees. In most cases, the water will not freeze solid (leading to cracked engine blocks) until the temperatures stay below 32 for several days and nights.

Do you need to winterize a boat stored inside?

Of course, as BOATUS states, the best winter storage space for your boat is “indoors, in a climate‑controlled facility with a backup generator.” This means that you need control over the temperature in your garage. A good garage door that seals out the cold will help keep your boat safe over the winter.
