buzzman Posted January 13, 2016 Share Posted January 13, 2016 Hello- my drain plug is seized and I will order a new assembly from Joe at Cecil. Any advice how to remove and replace? What type of sealant and do I drill new holes? This job has me a bit nervous. Thank you Quote Link to post Share on other sites
Chap243 Posted January 13, 2016 Share Posted January 13, 2016 I would suggest keeping the original holes as long as you still get good screw bite. I would use 3M 5200 liberally in the holes and behind the brass outer ring. Before you try anything I would make sure that you cannot get the plug out. I cant imagine it sealing itself closed under normal use. Quote Link to post Share on other sites
cyclops2 Posted January 13, 2016 Share Posted January 13, 2016 Ask Cecil w hen you order. Have some pictures for them to see. Any chance last person cross threaded the plug into the hole ?Or a dumb gorilla pulled it too tight. Not sure ? Pay some marina.What the hellllll is wrong with mechanics ????? Worst case ? There is all of 10 pounds of pressure there. And a bilge pump if it weeps a little each week. Quote Link to post Share on other sites
alka2710 Posted January 14, 2016 Share Posted January 14, 2016 PB blaster and a pipe wrench. Might want to epoxy the screw holes over and re drill before installing new one. Too much pressure to take off and you def will have to epoxy the screw holes.Al Quote Link to post Share on other sites
mikeofwarr Posted January 14, 2016 Share Posted January 14, 2016 Make sure you are turning the plug "Counter Clockwise" when removing. Easy mistake to make when removing nuts, bolts, plugs, etc. Quote Link to post Share on other sites

Wingnut Posted January 14, 2016 Share Posted January 14, 2016 Does your brass thru-hull gar-board drain have a bonding wire attached? If so, then that one screw is not a simple screw, but is actually a machine screw with a washer and nut on the inside. Depending on the size of the boat, and whether or not it has shore power options, some are bonded and some are not. If it were mine, I'd center drill the existing plug, and very carefully drill sequentially bigger holes until I could collapse the plug in on itself. Clean the old threads with a 1/2" NPTM pipe tap, and install a new brass plug (1/2" NPT) with Teflon tape. Don't know where you are or what boat you have, but if you are local to Upper Eastern Shore Md., I'd be happy to do it for you. W Quote Link to post Share on other sites
