No, the bent tracking fin would not make it shake, it doesnt take much damage at all to the prop (most likely), shaft, or strut to make the boat shake like a belly dancer.

shake how? Like on acceleration or at high speed? I doubt it would cause vibration. More likely prop or shaft bent, possible alignment issue.
I prayed before I went yesterday and God answered my prayers, everyone was safe, no stumps. |

As it could be out of alignment something had to change to get it out of alignment.
Bent shaft, bent strut are the first things I would check along with the prop. The prop won't take it out of alignment but it will "shake it like a belly dancer" but so would a bent shaft. The strut being bent will take it out of alignment and also cause a vibration. |

For thousands of years men have felt the irresistible urge to go to sea, and many of them died. Things got better after they invented boats.

Agree with joe. Neither a bent fin nor misalignment will cause vibrations. Prop is probably bent- it seems unlikely to have bent the shaft or strut without damaging the prop. If you're lucky that's as far as the damage goes.
