Have you tried raising your engine up a hole? There's a good possibility your engine is too far down in the water. A 4 blade prop enables you to run a little higher than a 3 blade.

Edit!!

If your running 47 mph at 5500 RPMs and your gear ratio is 1.75 then your are seeing 7% prop slip which is pretty good actually.
