4 blade cupped or 3 blade?

I currently have a 4 blade cupped prop on my 17ft mitzi. I do about 27-28 mph. What would the speed difference be with a 3 blade?

Again I say -- call Ken at propgods in Sarasota. I have a three blade on my Banshee and my buddy has a 4 blade on his - both powertech. My boat goes about 4 to 5 mph faster and they get up on plane "about" the same. To be honest, his a little better, but not much. Call Ken - you will not be sorry. My prop is a modified 3 blade powertech - with a change in the cupping and some holes drilled in it to allow it to pick up rpms faster.
