Heaters and Winterizing
In parts of the country that don't usually get too cold, plugging in a heater in the engine area seems a lot easier than lugging gallons of antifreeze to the boat and filling the engine(s) with it. In fact, using a heater can destroy your engine. When these places do get cold, it's often accompanied by an ice storm that takes out the power. No power to the heater equals unprotected engine, which equals permanent damage and a new engine.
A destroyed engine may actually be much better than what else can happen when you use a heater for winterizing. An overloaded electrical system, a damaged extension cord, or a faulty heater can all cause your boat to catch fire and burn. Your boat neighbors are not likely to be happy to learn that your "shortcut" destroyed their boat, too. Take the time to winterize your boat properly this winter.
