Running the "M" prop I would think you will be approx. 1 3/4" below the pad turning 5800R's and 62-64MPH light. Also, Mark does wonders with the M props. I had him B & B one for me-I sold it to BassJunkie and I believe it is his fastest prop to date. He runs a TZX190 @ 68mph and change with a 175 Yam.
