Dan;
The “drain” plugs you mention are actually for lubricating the valve – kind of like the grease cup most of us have on our rudder shaft housing. The valve, as you have probably figured out already, is a tapered plug that looks like a big metal cork with a hole drilled across the centerline. There is a retaining shaft on the back with a nut that holds the tapered plug into the tapered body of the through hull. If you loosen the retaining nut on the back by 1 to 2 turns. Don’t remove it, just loosen it a bit. After your penetrating oil has had a chance to soak in a bit, tap on the retaining nut with a brass or wooden mallet. Neither the nut or the threaded shaft on the plug should be damaged. A sound tap or two will move the plug “out” a fraction of an inch and break the bond of the internal corrosion. When you disassemble the valve to clean up the corrosion, be sure you don’t damage the outer surface of the plug or the inner surface of the valve. A smmoth tight fit ( and a liberal amount of grease) is essentially what keeps water from leaking around the plug.

If you poured a liquid penetrating oil down the scupper, it may coat the plug but chances are most of it will pass through onto the ground. If you could figure a way to plug the seacock from underneath so the oil would be stopped at the top of the plug when you pour from the top it may then seep around the plug. Maybe some Play-Doh?

I should have loosened that tension bolt on the end. The thought didn't even cross my mind, but now it makes complete sense. I can try spraying from undneath/outside the boat which would have the same effect as spraying from the removed hose?

The good news is I haven't damaged anything so far and the penetrating oil is still probabbly getting in there and doing it's thing... The space around these seacocks is very limited so removing them would be a real bi*ch compared to servicing them so I'm really hoping to free them. They do look like really expensive and high quality seacocks and are well adhered to the hull. Thanks guys, will update with progress!

I did the same as you with no progress. I then got a hollow metal tube at the Home Depot to use as leverage over the handles, and seemingly without much effort (leverage working at its best$ I was able to work them open and closed. /J On May 24, 2018, at 12:42 AM, Dan <dgcorm...@gmail.com <mailto:dgcorm...@gmail.com> > wrote: I'm on the hard. I have these two giant bronze seacocks for my cockpit drain hoses. photos on google drive: https://drive.google.com/open?id=12TWUN1oiyiACR0IvaBKlEo2HqdzPMmqY I have no clue how old they are but they are totally seized in the open position. I've tried WD-40, a heat gun and a rubber mallet but can't get them to budge. My question is should I rip these out and put in some sort of replacement or should I just leave them. When will I ever want to close seacocks to the cockpit drains? Clearly the previous owner was not in the habit of closing these. What should I do?
