Motor Problem

[davides618]

I am running a Suzuki DF175 with a Mercury Bravo I prop. Saturday when we decided to head back in we ran into some mud trying to get on plane. After that the motor started turning high RPM with loss of speed. Basically if I normally run at 5000 RPM I would be running about 40 MPH(GPS). Now at 5000 RPM I am running about 30 MPH(GPS). Also normally to get WOT (6100 RPM) I would have to trim the motor up with the throttle wide open. Well now without the motor trimmed up and with the throttle at about 3/4 I was hitting 6200 RPM. The prop doesnt not look to have been damaged. I took the prop off and pulled the hub kit apart and it doesn't look damaged either. I was thinking about buying a new hub kit just to try it. Any suggestions would be appreciated.
