Replacing sea cocks, remove the metal ring?

[anonymous249243]

Hi,

I have a Jeanneau Sun Odyssey 50DS from 2009.
I'm replacing the tru holes / sea cocks, and come across a metal ring.
It looks like it's part of the hull, but it could also be part of the old tru hole...

Do these rings come standard on the Jeanneau hull for reinforcement? Then I let them sit.

Or do they belong to the old skin fitting? So I have to remove them.

Kind regards!

What is the black corrugated tube? The pink ring i wouldn't trust if metal. Possibly best to grind the whole lot out and start afresh.

I'd assume it's a plastic throughhull and the corrugations are the thread.

Looks really odd: if the black plastic is the through-hull body why not a plastic ring inside as well? Where is this on the boat - underwater?

That ring appears, from the photo, to be so well glassed in, that it is not going to fail. So why remove it, only to replace with something that may not be held so securely?

I’ve just replaced all of the Thru hulls on my 45DS with Trudesigns. It had those metal rings too and I managed to get them all off (one required a bit of persuasion!). I think that they were backing plates for the old metal Thru hulls. Boat back in the water and not leaking (so far…)
