spongy backing plate on intake seacock

[Sea Hunt Video]

Sea Hunt (Robert),

I made the plate for Mike using 3/8" GRP I got from McMaster-Carr several years ago. (What I bought: http://www.mcmaster.com/#8537K47) It's a greenish tinted vinylester layup that is very water resistant. So far I've made five backing plates for Loonsong and the one for Mike, leaving still enough material in the sheet to make my last backing plate when the time comes (Loonsong's original factory wooden engine intake seacock plate is still solid as a rock--the head and galley seacock backing plates were punky). I make two identical 3/8" plates and glue them together for a 3/4" plate.

Thanks Bill. The installation Mike did looks great. I will check with McMaster-Carr about the GRP. As of now I think I only need to install one backing plate for the raw water engine intake seacock. It looks like the other seacocks have good (teak ) backing plates. My plan as of today is to do this in the Fall when I haul out for a few weeks for some other maintenance, upgrades, etc.

Thanks again.
