What do you consider "Best Performance"??
Speed? Fuel Economy? Torque for towing? Hole Shot (Time to plane)?
Your Wide Open Throttle (WOT) RPM is right where you want it to be. Once on plane at WOT, trim the drive out until it cavitates, then immediately trim in until it stops. That will be your sweet spot. At that point, the RPM should be between 4500-4800 (the closer to 4800 the better.
If you add a blade or increase pitch, you will decrease the max RPM at WOT. This will more than likely increase top speed for a given RPM, decrease hole shot and add some load.
If you decrease pitch, you'll increase your max RPM @ WOT, however you'll decrease top speed and increase hole shot.
