    Pretty sure your prop is geared down and wouldn't be running at 4,000 rpm. The ratio varies on what equipment you have...

    I've never had shaft zincs come off. put them on and tighten them down. Then take a hammer and hit the zinc all the way around, this usually gets you another turn on the bolts (don't "tap" hammer, but not like you're driving a railroad spike). then take nail polish and paint a line where the bolts goes through the zinc. This prevents that part of the zinc from getting eaten so the bolt doesn't break through.
