Very little information to start troubleshooting but you have to start with the basics. Any loose or damaged rotating components, mounts, damaged/loose prop, oil level/condition of oil in lower unit. lower unit or middle section not secured or loose, etc., etc., etc.

Have you removed the LU to check for oil and freedom of rotation?
