Re: When to winterize? Do you boat in winter?
Personally, I could not sleep knowing the only thing between me and the loss of my engine was some type of heating device, be it a light bulb, portable heater or electric blanket. Well, the book of "How I Cracked my Engine Block " was written by some wise-as$ Floridian who carved out bad Karma by mocking northern boaters, so there's no shortage of people willing to take chances. I believe the cover picture is the author holding a heater that failed and a weather report that showed the low temp was 'only 33 degrees for the area'.
The number of cracked engine blocks from freezing because people depended on something other than draining the water = thousands every year.
The number of cracked engine blocks because people properly drained them = Zero
