Do I really need to winterize my MasterCraft even if it is stored in above freezing temperatures?
It is a good idea that all engines be checked and winterized before storage, even when you plan on storing the boat in a heated area. Antifreeze lubricates hoses, impellers and seals, which will help to prevent drying and cracking. Fog oil helps to lubricate pistons, valves and cylinder walls which protect your engine from corrosion and long term wear on the engine.
