Re: 3-blade fixed prop recommendations?

I'm doing a gasoline to diesel repower and am working on the same issue. I think what matters in performance is having the correct pitch/diameter/blade area combination. If you want to get into this the ultimate reference for us amatures is Gerr's "Propeller Handbook". Besides all the basic info it gives the info so you can make your own calculations. I went to Michigan Wheel and they entered thier data into thier computer and were failly close in pitch however thier blade area was too low for the cavitation curve calculations so it was good to have done them. You may find the book at the library.
