[C320-list] Winterizing Engine

[Jack McDonough]

Guys:

Assuming the "water pump" does its job, how much antifreeze does it take to 
complete the winterizing? In other words, what's the raw water capacity in 
the system? I've had times when I must have pumped at least three gallons 
through before I saw the water turn pink, or whatever, coming out the stern.
