Prop wear?

[Seahawk]

Ran over a mostly submerged branch/log of some sort. Heard it and felt it go under the boat. Immediately put in neutral. After it passed started to throttle up, once hitting about 10mph started to vibrate pretty good so thought for sure prop was damaged. Putted back to pull boat out of water to inspect. Under 10mph no vibration and made it in. Upon putting boat on trailer so could visually inspect, no nicks, bends etc to prop or shaft. Thinking maybe some weeds or something maybe got wrapped around shaft and came off while putting through no wake zone and loading on trailer. It was end of day and last night so never put boat back in to go test to see if vibration was gone now that I knew I had no obvious damage to prop or shaft. When getting home spent more time inspecting again and noticed back side of prop appears to have wear spots on 3 of the 4 blades. Curious if this is normal from use? Prop is about 3 years old or so. Is this wear enough to cause very noticeable vibration? Tried to get pictures, bottom blade has no wear but left and right do in the picture. Top blade also has wear, just didn’t capture in picture. Planning on taking it back out this upcoming weekend to test. Probably more detail than need for my question but wanted to give the whole story of what led me to my question.
