removing seacocks

[scottwilliams]

I need to remove the seacock that is no longer used for the head. It has been plugged after previous owner installed holding tank. It appears to be a threaded connection. I was going to try a chunk of steel from the outside with a pipe wrench. Am I on the right track?  Any tips - thanks Scott 269

There should be one on the port side and one on starboard .
If it is like the ones I took out of #45 last summer  , the flange itself was thru bolted .

Get some P-B Blaster at the auto parts store and spray the threads several times for a couple of days if you can wait that long , it should turn off/out with little resistance .
You can turn the flange from the inside too , after you remove the bolts .
Then  glass the holes .
The Blaster really helps , don't use WD40 .
