Current prop is an aluminum 3 blade, but that's all I know now. It is in need of replacement and I really want to maximize my ability to pull people out of the water.

I don't know my typical WOT RPM, nor my typical load (but say 4 people typcially when skiing).

What more is needed in the way of spec's and data to properly size a prop?

Thanks,

Your current prop has the pitch marked on it somewhere. I would say you will be looking at a replacing your existing 19P or 21P with 17P using 3 blade or 18P using 4 blade. Check in with local yards, they may have some used props you can try out.
