David,
When I bought my 35-1 the raw water thru hull valve was flopping around
(boat was on the hard). The original installation had just a small
piece of plywood between the flange and the inside of the hull which
came loose. I epoxied a piece of 1/2" thick McMaster Carr g-glass on
the inside of the hull with nuts epoxied in recesses on the underside of
the plate, then put on an integral thru hull/valve. Something like this:

Wound up doing it to all the others except the two way back under the
steering cockpit, which I'll get to some day. May be overkill but I
didn't want more of them coming loose.

While she’s on the hard, I plan to replace the seacock gate valves
with ball values on our ‘75 C&C 30 MK1. Can anyone offer the benefit
of experience in doing so? Are there tricks to stabilizing the
through-hull fitting while unscrewing the old valves? Is it best to
replace the entire through-hull fitting?
With thanks,
David
