Richard is right you can throw a blanket over the engine or use a heat lamp or bulb it would take alot more than One night to do damage. if anything would freeze it would be your heater core ballast pumps just pulling your block drains and exhaust manifold drains will not protect you from damage. you have trans coolers,fresh water pump,shower,heater,three ballast pumps malibu has six ballast pumps. mercruiser has a fuel cooler.
