Another mid-shaft bearing question

[Jduck]

I have an 08 gp1300R and it started cavitating really bad. Like i would have to make a couple circles before getting up on plane. It has original impeller, so i assumed it was the problem. I pulled pump and shaft and the prop looked good, but i could see where the shaft has rubbed inside of plastic canal. Does that mean bearing is gone? Thanks for any help in advance.
