Broken blue seacock

I'd buy the tap and do it yourself... should be easy, assuming you can get to it. I know mines tight, and I believe we have the same setup!
 
I believe the plugs are 1/2" 13. Maybe gently tap it so as not to create new threads
 
Yeah, try tapping it yourself. It should be pretty easy. I "think" the threads are 3/8"-16, but double check. That's a common sized bolt that you can get at any hardware store - check to see it threads into a more accessible blue plug area, before contorting yourself.

In the end, it's the rubber o-ring that seals, so as long as the new plug screws in, you're good.

Skunk may be right on the thread count... 1/2"-13 is also a common bolt size, though.

You "may" be able to clean it up well enough with a bolt.

This plug is right up front. Now the primary bilge pump aft is another story.

Ahh... you must have BIII outdrives... much easier than mine with V-Drives!
 
Yes- much easier. My research tells me different thread sizes. Some say 1/4" NPT?
 
I tried to remove it with a screwdriver as described above. I got great torque on the plug but it just disintegrated leaving plastic in the threads. I tried to get the plastic out with a pick but no way. I may have to have it tapped. To get the boat to the marina I was thinking of using a temporary plug - maybe some type of expansion plug. Any other suggestions? Or should I tap it myself. The plug is on the water pump. I don't want to ruin it.


Sounds like it may have been installed with 5200. Perfect example of where not to use 5200. They make a solvent used to soften and remove 5200.

is it possible that the engine overheated or maybe manifolds run dry and overheated? That would possible melt the plugs into the threads. They should not be locked in like that.

You have 3 guesses now... You need to get a plug and figure out the thread size for sure ..... I remember looking at this a number of years ago and it wasn't any standard thread (4th guess) ....Just be sure before you tap yourself a new part.

You are right. I like to try to figure as much out as possible in advance since I am quite far from a good hardware store where the boat is kept

FYI

I just checked one of my spare blue plugs. It threads into a 1/2"-13 die with just the slightest amount of resistance but the die doesn't shave off any blue plastic in the process.
