I have a 04 stratos 200XL, yamaha sho 225 I had the ECU reprogrammed to 300 HP with 6500 rev limiter. I am running a turbo FXP 27 pitch with a hydrolic jack plate at wide open throttle it will run 84 MPH GPS but that is at 65000 RPM I am wanting to get the RPM's down to 6000-62000 RPM's. I am thinking 28 or 29 pitched prop what do you all think? I would appreciate your help.
