I just found that my prop is slipping on the hub. There are 3 screws going into the prop and into the hub but it looks like they all sheered off. I have a feeling they were put there by the previous owner in attempt to fix the slip. If I put the prop's hub in the vise I can turn the prop itself fairly easy over it.

Is this all normal??

One more thing, If I swap this prop out for another I only fish in bays and rivers with this boat (15' 1971 MFG NIAGARA) and the prop is a 10.5x12. Should I change the pitch or diameter or is this a good size and pitch for this boat?

Thanks in advance!
