I just bought some parts from a guy down here in Washington State who had freeze damage to his engine (cracked block) from last year on Puget Sound. We get temperatures down in the 'teens now and then that can last for a week or so.
Having said that, I don't add antifreeze to everything in the winter, but instead I drain the fresh water systems, make sure my engine coolant has antifreeze then leave a little heater in the boat for that week of cold weather.
