Yamaha ox66 lower unit. It has a Bob's cone it and functions as a spare for me, BUT it could use some work. Propshaft is out about .004-.006", at least it was the last time I measured it. Bearing carrier is worn on the starboard side, as is the case. Pinion gear has a small chip on coast side. Someone must be able to use this thing. It is complete with a good water pump and I have a spare pump kit for it new in box. Make me an offer!
Thanks, Mike.
P.S. it has a Bob's torque tab on it as well.
I can't seem to post pics at the moment, i'll get to that asap.
