Bravo 3 Prop Shafts .045 & .025
 

Boat has 250 hours on it, it is a 2006 formula 28 SS.
I have a vibration so I went to time my bravo 3 props, and check run out on shafts before sending props out for checkup and balancing. Found excessive up down shaft movement on both output shafts. OneDrive is a ow200,000 serial number and the second drive has a ow900000 serial number. The newer drive has less up and down movement, .025. The older drive with serial number 200000 has . 045 thousands up and down movement. Very disappointed.
What do you guys suggest, complete drive inspection, or just lower gearbox bearing reshim?
Any recommendations for Milwaukee area for a good mechanic?
