The original plywood backing blocks for all of my thru hulls are rotting, so I'm trying to replace them, mostly following Maine Sails recommendations using the Groco IBVF adapters. But ...
I decided to trade some dollars for time and buy the Groco backing blocks rather than making my own. I've read several other threads here where people have successfully used them.
When I got them, I noticed that the little threaded inserts are Brass instead of Bronze. Isn't this a really big deal? (or am I overthinking here?) Will the zinc not leach out of the brass in just a few years leaving just crumbling copper?
I really hope I'm wrong here.
Thanks !
