I have an 83 3.8 stern drive and last time out I hit a log or something. It damaged my prop. I had the prop rebuilt and I was checking the shaft to see if was bent with a gauge I have. With muffs on, out of the water the shaft was true and straight. However, I noticed it made a noise shifting it gear. I realize in water it wouldn't be heard and the shift felt normal. So my question is, is this normal. I don't remember this noise last time I shifted out of water but then it's been a few years since did this and the shift was out of adjustment at that time.
