Re: Greased or oiled ?
Make sure you lightly grease the splines at the top of the driveshaft, and make sure the o-ring is in place there. You could pressure test the lower unit to see if there are any other leaking seals. There is a driveshaft seal and a propshaft seal, and of course, the seals on the oil drain and vent screws. The propshaft seal sometimes gets fishing line wrapped around which compromises it. If you drained the L/U oil and it wasn't milky and no water came out, you should be ok.
