Catalina 22 Trakai Lithuania
Hi everyone, just bought Catalina22 '85. During preperation for painting decided to remove keel for painting and also to check the quality of bolts. While unscrewing two of them broke. Maybe anyone knows how to change them? I mean is it necessary to make holes from inside the body of catalina or there is something more to know?

They will have to come out. I had a similar problem, (not on hangar bolts though).

I bought reverse drill bits from harbor freight and started to drill them out using reverse on my drill.

Before I drilled the bolt out, it simply unscrewed itself.
