Vibration

My 200 Yamaha motor is vibrating at low RPM's. Is this coming from my prop? If so, what would it be?

that would be my first guess. a bent fluke or even a bent shaft. is it on a trailer where you can spin it and check for alignment. the end of the shaft should spin perfectly symetrical. you should be able to see if a fluke is bent. pull the prop and check for line around the shaft too.

Spin prop and watch the little indention in the end of the prop shaft.

Its spins fine, no issues with shaft.

What about a nick in the prop? It looks like the motor was to low and nicked/scuffed the prop while loading.
