I didn't want a stainless or brass ball in my new seacocks, and in 
doing the research I found a few options that fit the bill:

1) Spartan bronze seacocks:  Traditional bronze tapered cone. US Bronze.
2) Perko Bronze seacocks: Acetal ball. US Bronze.
3) Conbraco Apollo seacocks: Chromed bronze ball. US Bronze.

I was lucky in that all my old gate valves/through hulls came off 
easily -- ahhh, freshwater.  I did replace my engine intake with a 3/4" 
intake seacock/through hull just to bring it up to industry standard.  
I also removed the metal strainer/cover from the outside and epoxied 
the screw holes closed (prefer a "real" intake strainer inside the 
boat).

For the cockpit scuppers, I put in 1-1/4" seacocks/through hulls with 
"normal" pipe-to-hose connectors on them.  I allowed for future cockpit 
scupper fitting changes by the option of replacing the "normal" pth 
connectors with Groco "full flow" pth connectors, which go into a 
1-1/4" inch seacock but take a 1-1/2" inch hose (most current cockpit 
scuppers I like are 1-1/2" in diameter).  Of course now there is a 
restriction there with the "normal" pth connectors, but that's how they 
usually are, so it's no different.

I used electrical-grade pre-made fiberglass for backing blocks
