9.8 Slow rythmic clicking

My 9.8 started making a regular slow clicking noise I think from the lower unit.
It's timing changes with the revs but I would guess it's a click every 30 or so revolutions of the prop.
Is there a part that revolves so much slower than the revs suggest.
What's it likely to be , doesn't sound too bad but guessing it will get worse before it gets better.
Quickest checks?
Look forward to any suggestions

Thanks for the reply.
yes two teeth missing off the Drive shaft bevil gear B.
Only thing that had me confused was no retaining nut to hold B in place. just fits on the splines of the shaft.
wondered if it had fallen off and ground away but there is no thread in the shaft to take a nut so i guess thats right.
Just have to find a new gear here in Panama.
will i need extra shims for reassembly to adjust play or is it not that critical on these smaller engines.
Any suggestions gratefully received.
