Wanting to replace some older Groco valves that you can't get parts for anymore. Should I replace the thru hulls at the same time or can I just replace the valve if the thru hull is not showing any signs of problems. Can I just clean them up. I haven't come up on thread about using the bronze vs Marlon valves, but with price close, the bronze seem like the choice though I did put a couple Marlons in my last boat that were fine for the 7 years I had them. Any thoughts appreciated

Thanks

Groco valves or seacocks? These things usually last forever.
What kind of parts are you looking at replacing?
