Every time the prop hits something...... the closer the bushing gets to "spinning". Over time, the bushing weakens and could spin out the next time the prop hits something or maybe while you are just running in open water.

Thanks for the detailed reply, Gerald.
is there a way to check to see how badly damaged the bushing is before it goes out or is it one of those things that you just have to wait for it to fail (most likely when you are 40 miles offshore with a storm approaching).
