Sounds like you've spun the hub on the prop.

It's a hard rubber sleeve in the prop that is supposed to absorb the shock and protect the lower unit if you hit something with the prop.

When they wear out the prop shaft spins but the prop doesn't spin at the same speed.

If the prop is in good shape you can buy a new hub kit for it.
