My dad had an old 18HP Johnson that kept sheering the key. One solution was to use an aluminum beer can and make a shim that fits between the shaft and the flywheel. Other products like Quick Metal or LocTite offerings also can help.

I agree with other posts. Pull the flywheel and check everything underneath.
