I have this hole in my bilge and have been fighting to even get a quote on fixing it. Wondering what it would take to do it myself. Its about 1/2 inch wide.

Some sources online say 5200 will be good enough others say it needs fiberglass. The disk is what I presume to be a cap or something over it.

What would this forum suggest?

It's nothing structural. If the foam is dry, just fill and smooth it with some good epoxy. When it hardens, sand it smooth and paint white.

If the foam is wet, it will start causing any wood to rot. You can either ignore it until you have to fix it or cut it open now to investigate.

Foam is dry, I do an inspection of the bilge before going out each time so it had less than a day to sit before I put some tape over it until I found find a solution. I don't feel any moisture.

Seems like should be an easy enough fix. Here's hoping goes well 🤞

Dig the foam out a little bit, like 1/8 of an inch, and sand the edge of the hole with some 80 grit.

I got it mostly fixed a couple of days ago. Some gelcoat ended up a little soft and a crack in it so I'll likely do another coat over it but the hole is patched up enough until I either have a professional look at it in the fall or it stays that way forever.
