There should be a way to adjust the shift linkage on the starboard side of the motor that might help. I'm guessing on the back side of the shift handle, there will be a screw that can be loosened and it will allow you to adjust the shifting. If that screw has come loose and the linkage moved, that would explain the potential clunking.
Worst thing I can think of is you may have some stripped gears in the lower unit...That you can check as well. If the motor is a pin-drive (non through hub exhaust) you can remove the prop and actually remove the lower part of the housing. There is probably a gasket that could get replaced as well, so if everything checks out down there, you've just done a good worthwhile inspection of the lower unit, and have a newly sealed lower unit.
My gut says linkage...I'd start there...
