Is this enough prop damage for a massive vibration?

We were cruising along around 12mph when all of a sudden the boat has a debilitating vibration. Our first assumption was we hit something but we were in deep water. It could have been a small log though. We immediately stopped. We cruised back at 3MPH. Turned boat off, restarted it, and tried once to slowly accelerate. Massive vibration. The boat is not driveable. Pulled it out and see minor prop damage. I’m praying this is enough to create the vibration, as we have a spare prop, but i fear it’s something worse. We owned an older outboard with more prop damage than this and zero vibration.

I see no damage to the shaft.
