As I understand, either the shaft wasn't straight enough or the prop flange wasn't mounted quite right. So the shaft or flange wobbled slightly with each rotation.
Anyone who wouldn't put a dial indicator on the prop flange before shipping it out should be fired IMO. That would be the minimum level of QC required on a redrive. I'm not sure how you'd have significant runout on a CNC machined shaft and housing. Angular displacement maybe from the case bearing bores not being perpendicular but even that would be hard to do if fixtured solidly.

Shipping damage?

Most props this size use SAE 2 and I;d guess so therefore do the drives. Such is the case for most drives I've been involved in the 150HP+ range. I'd like to find out more from Len first hand.
