4 and 5 blade props?

[Bigshrimpin]

I tried a Merc highfive a while back when I owned a 20MA. It's sOoooo smooth and vibration free compared to a big 3 blade prop like the mirage plus. I could bank the boat hard 47mph and hold water . . . most fun I had driving the 20. Cruise and Top end numbers were lower than mirage plus by 3 or 4 MPH. If you get one of these props they are designed to run a bit higher than a normal 3 or 4 blade prop.
