Ok, hopefully last question for a while......on my AQ140A, on the starboar aft portion of my engine block is a brass fitting with barbs, it is unused, however on parts engine I purchased, it has a rubber hose going to the heat exchanger ( I believe). is this the block drain for winterizing? Help please identify, and explain it's purpose
