Replacing vertical thru-hulls in a 76' 23 SF

[John3325]

Whose taken on the task before?

Thinking about replacing the ones in my 76' 23 just to say they are done and never have to worry about them. Reason for the post is I am looking for some insight on what to expect.

I have redone mako thru hulls before by sanding some PVC pipe and glassing into the transom. Can this be accomplished for those pesky vertical thru hulls that go straight from the deck down through the bottom of the hull? Should I just get new bronze and buy the tool and seal with 5200?

Any insight to taking on this project is greatly appreciated.
