I looked at your graph of mph vs rpm and I think I'm very close- I was expecting a faster cruise speed per rpm with the 4 blade. I have to say I am happy with my current blades, I know the 4 blade are less vibration and less harsh on the lower units. I dont think I'll gain any real performance advantage though.

Yes we have spoken before, and yes you are correct about the vibration.

I had 15 x 32 3 blade MR cleavers on the boat, and it was 1-2 mph faster; however the harmonic vibration was considerable, and I was chewing up props and gear cases. These 4 blade props are just so smooth and strong.

Please remember that here in SW FL, the heat and humidity take a toll on engine performance.
