No doubt that rig should be very near 50mph. As Lambeau stated, if you can find a good prop shop that will allow you to demo different props, by all means do so. If you find a tempest that gets you close to your recommended top RPM, then you are very close to having your rig optimized....from there, you can move the motor up a hole...possibly to the top hole and get those RPMs to the max, and gain on the top end. There is a compromise, there, though...hole shot may not be as strong, but it will be decent. I believe the tempest series of props have vent holes in the hub too, which will allow some exhaust to exit along the blades during hole shot...this lets the motor get into a higher RPM Range and jumps the boat up on plane quickly...
