Those are the wrong props. You need Mirage Plus 23" or Bravo 1 22". You need to see 4400-4600 RPMs.
The Mirage Plus will give you better top end speed and the Bravo1s will give wicked mid range acceleration and a lower cruising RPM at the same speed.
I have a good friend with the same boat, so I am sure about this. We changed his exhaust and hit the rev limiters with the Bravo 1s.
At 4100 RPMs you're not in your engines power band.
