My 32 has the strut mounted with 4 bolts that screw into nuts glassed into the hull, after trying to remove this strut once to remove shaft I had to drill out one bolt and reinstall with a longer bolt and the nut inside the bilge (I was lucky to have access to the area)
Is it possible that yours is just loose and just needs tightening or did you hit something with it.
I do know now that its critical how the strut is aligned with the shaft so I'll never remove mine again if I don't have to
