Seacocks ?? Open or Closed ??

When we purchased our boat the surveyer recommended changing out raw water pickup hoses. They were in less than good shape. I went through and checked all of the hoses. This was the bottom side of our starboard exhaust bypass hose. It came apart while I was trying to remove it. Don’t think I would have seen it if I couldn’t fit behind the generator. Doubt any paid maintenance personal would either.View attachment 77578
Good God that's scary. How old was that hose?

My guess is as old as the boat. They were all showing signs of rust from the reinforcing wiring but this was the worst.
 
Mine stay open but surveyor checked the hoses and sea cocks August 2018 when we bought it. We only have sea cocks for AC, macerator and one for the toilet water intake. The only one that stays open is the AC but I cycle it a couple times a season when I clean the strainer and the hoses all look new.

Jesus that is so scary.
 
One of mine has been stuck open since before I bought the boat. Hauling for paint next week, and will have it replaced then. That said, I leave mine open, but am very diligent about inspections and double-clamping. Food for thought, nonetheless.

Most, but not all, times they can saved. Some penetrating fluid and good 'ol fashioned leverage can help. Try a pipe over the handle (or a socket wrench in the square hole on the handle, if it has it) and just start working it back and forth. They're not cheap - so it's worthwhile to try and get it moving again. If you do, be sure to "exercise" it once a month.

Apparently you can upgrade older ones to include zerk fittings. Shop said, they typically plug the bottom and fill with penetrating oil and let them soak, if they aren't replacing them. I opted to upgrade.
 
If you are applying excessive leverage of one sort or another on the seacock handle, be aware of the force that you are putting on the valve & the hull. Best to have some "Stay Afloat" or plugs ready just in case you spring a massive leak.
 
Always open and exercised often... I have a cellular-based water alarm on the floor in the E.R.
