[C320-list] easy way to winterize the raw water and conform toABYC code?

[JJ Morrison]

i don't like putting plumbers antifreeze into the engine as it does not have any inhibitors in it. I put propylene glycol in the engine when the boat is on the hard and catch the overflow in a bucket and dispose of it correctly. I'm also investigating draining the raw water system and leaving the heat exchanger dry during the winter. Anyone do this?CheersJohnM1999#574
