Hi Tim, I apologize for such a delay in responding. We had some issues not getting notifications and we just saw your post. Have you been able to run it with anything yet?
A Mercury tempest 19 pitch, or Mercury Enertia/ Quicksilver Q3 in a 19 pitch would probably be a good starting point and see how it does. We have the Enertia 19 available to demo if you wanted to try it out, but not the the tempest. Feel free to give us a call ((941) 748-1527) if you have questions or want to demo one. Below is a link with some more info on the demo program

I just got the boat back. I started with a Rev4 17p that I already had. Got to 5100 RPM which is in range (5000-6000) but definitely on the low side. Can I have the prop repitched to get 400 RPM?

Hello Timd
The Revolution 4 seems to be a bit too much for this application. I would suggest that you try a Q3 or Enertia 3 blade 14 1/2 x 18. You should try to load the engine, but target to be close to 5700-5800.
Contact us if youwish to try any prop.
Thanks
