Earlier models were metal and need to be replaced every few years. WARNING do not mess with it unless you can be sure to be hauled on a moments notice. The typical failure mode is the nipple breaking off flush with the shaft seal. Once that happens there is no way to stop the water ingress and unless you're hauled ASAP you will sink.
One quick way to stop the water ingress is to put some plumber's putty or modeling clay in the hole and then wrap it with the silicone-self-fusing "rescue" tape. That will often hold it long enough for you to get the boat out of the water. Carrying a couple rolls of the stuff aboard your boat, in the emergency tool kit, is usually a good idea.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Dog, the way the seal is mounted it would be a real struggle to wrap tape around the seal. Now maybe a repeat act of the little Dutch boy and the dike might work

That is why I mentioned the need for plumber's putty or modeling clay.

Had a plastic stopcock on a Yanmar diesel inboard blow out on me last summer on a friend's boat. We fixed it by jamming the cut off tip of a pencil into the opening the plastic bit left behind and then wrapping it with Rescue tape. It held for long enough for us to get back home (three days away) and get it replaced. Interestingly, the piece that broke is discontinued, and the replacement piece uses a bronze stopcock, rather than a plastic one.

Amazing what you can do when you have to isn't it? Sounds like a good McGyver fix.

Did much the same on a transmission oil cooling line many years ago on a Ford E350 van using a leather keycase and some speaker wire. That repair lasted over 3,000 miles, mainly because my father forgot I had done the repair and didn't replace the transmission cooling line until he saw it on the next oil change.
