Thanks SD for that clarification.
Tom -- I have all of them closed except for the engine raw water, dripless shaft, and one other one that is stubborn. I didn't antifreeze any of them because it's salt water in them and they are below the water line.
I don't like the smell of antifreeze, but perhaps I should go around and put antifreeze in them?
Great minds discuss ideas;
Average minds discuss events;
Small minds discuss people.
The best minds discuss sailing, anchors, batteries, rode length, fridge-or-not, freezer-or-not, and guns-on-board. I don't know why. It's a mystery!
