I am leaving my boat in the water this year (hood river, or) and wanted to know if I should leave my thruhulls open or closed for the winter?
I thought someone told me something about them, but had forgot. The water in the river doesn't freeze, but a boat sinks in my marina every two years because one of the thru hulls cracks...
If your not going to use the boat I would close them.Your not going to use the sinks so why leave them open. I would also pour some antifreeze down the drains to make sure the water above the sea cocks doesn't freeze.
You have water in the hoses up to the waterline level. I'd pour enough antifreeze into each hose so that the water is pushed out, and close the seacocks as it's running through. If you have a fixed head, that means disconnecting the inlet hose and using a funnel to pour antifreeze into it, or maybe pouring it down the anti-siphon vent (as well as into the bowl). It's a good idea to keep seacocks closed year-round when not in use. (The exercise is good for them.)
Question: Do you have the factory-original "to-hulls" (bronze pipes stuck into blobs of epoxy inside the hull, with no disk or mushroom on the outside)?
