    You might have an issue with the drive shaft rust fused with the base of the crankshaft. This can happen when the carbon seal and or o-ring are not replaced along with molly lube to protect the drive shaft and crank splines. The carbon seal, oring, and spring assembly help to form a seal to protect from water intrusion into the crankcase and also protect the drive shaft and lower crankshaft splines.

    If you can not drop your lower unit this may be the issue. Please post some pictures of the motor and lower unit, it may shed some light on your problems.
