20' mercruiser 4.3 mpi prop?

[66moppie]

I am closing in on my restoration of my B 20 "Moppie." I really am interested in a 4 blade prop to provide an economical cruise and the ability to plane at low speeds. Any suggestions is appreciated. I know I have not provided much to the forum but questions, but promise to post photos as soon as the restoration is complete.
Thanks again

I have a B20 '66 also that I still need to start. I've been asking questions for years and still haven't put a sander to it. There used to be alot of info on the B25 site that disappeared. As with a lot of the B31 guys that experiment, find a prop shop that will let you try a couple of used/repaired ones to dial it in. I would think with the computing power available these days, it shouldn't take too long.
