Should I replace this thru-hull??

I was planning on replacing some of my thru-hulls, wasn't going to do this one originally but now I'm wondering if it too should be replaced? It looks ok to me on the inside but the outside looks scary ... never done this before so I don't know what is normal. Thanks.

Is it rough because of pitting or is it from the paint? But if the others are bad and this is the same age I would do them all.

That derelict boat was another dream for somebody else, don't let it be your nightmare and a waste of your life.

It does seem to have been painted (are these bronze thru-hulls supposed to be painted?) but I don't know what the metal is like under the paint.

Remove the paint and get the through-hull nice and shiny, and if you see spots that are pinkish compared to the rest, it has started to dezincify, and needs to be replaced. If that is the case, then you should replace all of the through-hulls as likely they're much the same age and probably in pretty similar condition. Here is a photo by Maine Sail that clearly shows the difference....

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.
