S2 11A yacht propeller size?

[cptmike1988]

I have an S2 11a with a M35 universal diesel and currently have a bad folding prop.
Lookin to change to a 3 blade fixed.

Any ideas on size?

I don’t know the right size for a fixed prop, so I’ll be “that guy” that asks a different question instead of answering yours . What’s wrong with the folding prop and what type is it? Some of them can be rebuilt, and the sailing (and even motoring) performance of a folding prop is substantially better.
