At what temp is it necessary to winterize plumbing?
My engine and holding tank are done, but I haven't yet put any antifreeze in the bilges and pumps, and the fresh water system hasn't been done yet (planning to use vodka for that).
With a forecast low of 25 degrees tonight (high of 40 today, 36 tomorrow), is it imperative that I get this done today? The rest of the week will be a bit warmer (lows 27 - 31 degrees, highs around 40). The boat on the hard.
