Help with Prop size for 200 evinrude outboard

[bumpdraft]

Ditto on the 15" diameter. When I bought my 23 it had the original 235 on it (83) . Around 1994 or so, I put a 200 Ocean runner on and used the same prop. Most of my time in the boat is in the ocean and I think the larger diameter, less pitch handles the waves so much better.
