Bronze – good old made in the US of A bronze. Real stuff – none of that semi-bronze made in Europe that came with the boat and that became dezincified. None of that cheap crap from China. Ugly stuff – DON’T DO IT. This is stuff that’ll last for for thirty years, not seven.
The value of the new bronze thru-hulls, fittings and valves is about 0.17% of the value of the boat. Now I consider that cheap insurance. Plus, I get to rebed all the fittings in 4200, NOT 5200 (see earlier post). If I ever, or the next owner, have to remove the fittings, I will not be cussing myself or being cussed out for using the less desirable bedding compound.
Discoloration is still a possibility (you know, turn to green like bronze does when around salt water) but I may have a remedy for that as well. I read somewhere that a nice coating of Boeshield T-9 will do wonders to keep the bronze looking spiffy clean. We’ll find out because it has been applied generously to all exposed surfaces. I like clean looking. Maybe not eat out of the bilge clean, but clean is good and doesn’t smell, either.
Still being toyed with is the idea of bonding all the thru-hulls together into a common ground. Purpose for that is to reduce the galvanic potential as well as serve as a common ground for any potential lightning strikes that may be attracted by the 62′ tall aluminum lightning rod called a mast. Zaaaapppp.
