Did you bend the prop for extra rpm's?
1mm is 100 rpm's.
Maybe that will help.

What mods are on the ski? 8100 with a 15/20 does'nt sound like anything is wrong to me umless you are running more boost than an x-charger. Also a 15/19 3 blade will turn very close to the same rpm as a 15/20 4 blade. Keep in mind that the rpms only read in 50 rpm increments on the 05s.

Are you monitoring boost pressure, fuel pressure on it?

Yes, I would expect a rxp turning a 15/20 at 8100 rpms to be in the 77mph range. Being that it is on going 74mph I would be looking for a drag related issue such as a broken intake grate , pump shoe, or a severely trashed wear ring wich I assume you would have noticed while switching props.
