Default Bravo XR props haft

Lost a blade on Bravo 1 labbed 4 blade today at about 6000 RPM. BIG vibration and came off plane. Now checking the XR prop shaft. What is the max out of round tolerance?
Update, PS still in the drive and put a dial indicator on the PS. It is .010 out. What is Mercury's recommendation for max out of round in the DS still in the drive?

Talked to Dick OSO "Mr. Gadgets" about both prop shafts runout and in/out measures. We will going to reset the torque on the prop shaft bearings and remeasure. At a min, we expect to be able to finish the season. What I learned is this is something that should be checked in a high HP application....more offen than never.
