Comments about Star Brite Pure Oceans -200F Super Concentrated Antifreeze, Gallon:
Carefully read the description of the -50 antifreeze on the West Marine website. Basically it says that the -50 antifreeze starts to freeze at +14° and plastic pipes will burst at -10. -10 is not unheard of in Boston but even worse is that if you drain your water tank, you may still have 2 gallons or more of water in your tank (likely more for big Sea Ray tanks) that you could not get out. 2 gallons of water in 5 gallons of antifreeze raises the burst temperature 20 degrees! No amount of -50 antifreeze can correct that, but adding 1 gallon of -200 antifreeze will.
