Thank you, Dennis,
I like the idea of the reverse flow with a pump. Sounds like it will use a lot less antifreeze to accomplish the same result. Appreciate it.
I am curious how to winterize the cockpit and aft cooler chill plates and AC on a 2007 Grady White Express?
Is the fluid that runs through the chill plates raw water or am I just winterizing the raw water that cycles through the AC/Cooler pump?
If that is the case, should I just disconnect...
