Myself, I'm using the Forespar Marelon flanged Seacocks,
with Marelon
through hulls.. (objective is to have all
non-metalic/non-conductive
fittings below the waterline)

The flange bolts were a problem so I used flat head
machine screws and
counter sunk the heads and epoxyed over them to prevent
contact with the
water. I will have to keep an eye on these over time to
see if there is any
evidence of water intrusion..

Steve,
Are your machine screws stainless or other metal? If
stainless, keep an eye out for corrosion under the epoxy.
Stainless doesn't like to be deprived of oxygen, as you
know!
