Hi , I have a loose marelan seacock on a brass thruhull it weeps saltwater ocasionaly. the boat is in the water and Im hetting a little worried..
I tried to tighten it, but it wont snug up. There seems to be some kinda white gunk between the brass male thurhull and the female seacock, It looks like some kinda old glue and its dried out and crappy lookin..
Can I try to tighten this thing while in the water, or do you guys think I gotta get hauled out to do this. In and out is $300 ouch !
Ide hate to break up the white gunk while tightening, I could end up with a real leak.!
The thruhul looks pretty good so all I have to do is swap the marelon seacock for brass. right ?
Saildog was saying bad things about marelon on brass, IT makes sense that expansion - contraction would eventually ruin the glue..
Thanks for ANY help on this could post a pic...
