Make sure you are using the correct antifreeze for your boat engine storage!
Don't use anything different than Propylene Glycol formulas. If you are thinking about using alcohol-based or blended antifreeze you should keep reading. Alcohol damages marine engines over time. Boat engines are made of many important rubber parts, alcohol will dry out these parts thus increasing the maintenance required to replace and repair these parts.
Save yourself added boat expenses and get the correct antifreeze this winter.
