[C320-list] Emergency Tiller Port/Hatch

[Ken]

Dave,
I was finding water in my bilge after heavy rains and finally found that access area was the source when I put a heavy coating of mar-lube around the gasket and edge.  It held all last season but started again halfway through this season.  Another fresh coat and it stopped.  Appears this will be an annual maintenance issue until I can fabricate a bigger gasket. Hope this helps.

The previous one was completely cracked when I bought the boat and the replacement still let in a fair amount of water. However, I used some Super Lube Silicone Lubricating Grease all around the seal of the removable plate and reinserted it and since then it has been watertight (almost 4 years).

I'm thinking one with a screw-in cap might be better to get a water seal (although I understand it would be more difficult to remove, especially if not opened routinely). Ideally a replacement would mount using the same mount holes (I know, I'm dreaming).
