I just removed a few thru-hulls to replace some rotten old seacocks. They are flush mount. Looking through the service yard catalogs, I can't find any that match my specs. The ones I removed look OK with just a little thread wear in the center. But, there is some red coloration. Can I re-use these?

Hey Cam. Can we please leave my liberal claptrap references in the off topic list?
I tried Groco. No fit. My hull is already beveled, but my thru-hulls are um unique... The guy at the yard said I should go with mushroom heads and fill the void with sealant. Sounds daft to me. Whattaya more experienced persons think?
Flush mount.
inside dia: 1 1/2"
thread dia: 1 5/8"
(no surprises there)
Flange dia: 2 7/16"
flange height: roughly 2/8"
roughly 2/8" on the 45 degree flush angle
again with the 2/8" from the 45 angle to the pipe.
hell, does that make sense? I am so ready to be in the know.
So I keep searching and searching but, no go with matching measurements.
my hull is countersunk to 2 1/2" but all the flush thru-hulls out there have a 2 7/8" flange. Does there exist in the universe a counter sinking tool designed to expand my mounting holes to a sweet 45 degree angle? Google is failing me. I'm tired of living on the hard. help me!.
Sounds like an Aerosmith song. "Living on the hard"
Why not use a router with a ball bearing - 45 degree chamfer bit? It may not be perfect since you have to follow the hull, but it will be pretty close.
If you wanted it perfect you have to make a templet for the router out of a peice of plywood, shim and hot glue it the hull - making it perpendicular and centered to the hole.
Gil...if none of that works out, you could build out with an epoxy slurry and fair to the hull, then mount any comparable standard mushroom head on there, or re-bevel to a different flush mount.
