Sorry, proper terminology would be seacock, not thru-hull.

This winters haul out projects focus on my thru-hulls. I've got some that don't close well (Popeye would have a rough time), some that leak and some that are down right scary. Additionally they are mostly of different makes. A few I think will clean up with the bead blaster but some have a really thick coat of patina on them that makes me wonder if some of the bronze components have leached from the fitting possibly compromising the integrity of the metal.
The main one I really wonder about it the old Perko 1.5 inch galley drain. It is a rich velvety green but doesn't leak. The design is from the age of steam but is still serviceable. The limited amount of space under there doesn't lend itself to spinning it lose from the thru- hull mushroom. I don't want to pull it unless it really should be replaced. I may be able to clean it up where it is.

What is the consensus on a green thru-hull? Shot?

The galley drain hose could possibly have been the original from 1979. My finger would nearly penetrate it at one of the bends. I was rewarded with a varied selection of knuckle cuts and scrapes during the removal of that hose and see why it was possibly never replaced.

I'm not considering any type of sea chest or modification to the intake/drainage arrangement.
