Vibration after running aground

Was anyone hurt? Hope not.
How fast were you going?
We’re you going straight or turning?

Most vibration issues are bent blades, bent shafts
But knowingly straying outside the bouys might make it hard to claim

100% agree. My bet is your prop is dinged. I hit mud and got a tiny chip on my SS prop, very tiny, and I felt it on the return to the dock. Amazed me how a tiny chip can be felt at he steering wheel.
