I'd look at boat supply places, and see what they have. As
someone else mentioned, might find a drain assembly you can
put on. Enlarge the existing hole,

I removed the existing hole. LOL.


bolt or weld or clamp on.
I'd dare to guess, others before you have faced a similar
challenge.

Best of luck, hope you find something soon, cheap, and just
what you wanted.

Interestingly I measured one of the rubber plugs today, and its smaller than
1" when compressed, and larger than 7/8" when uncompressed. Now I guess I
should crawl under my big boat and measure the diameter of the drain on it
just to be safe.
