Talking As A Matter of Protocol

I always shut off the raw water intake before shutting down, but 30 seconds is a bit much. 10 - 15 seconds does most of the available good, and I also have a valve for draining the raw water side of the exchangers into the bilge from where I pump the water overboard.
