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
