OK I have a 7.4L MPI with a Bravo 1. I have a 21P 4-blade stainless on now and seem to top out around 52 MPH, but this according to speedo. I also got a 21P 3-blade stainless with the boat. ANy guesses on the performance difference between the two? I was told the 4-blade gets the boat out of the water quicker, but the top end would be better with the 3. As I know nothing about the difference in props can someone educate me?
