Bad noise on my 25 Merc

Any updates on this problem? Just curious.

Oddly enough, I have been out twice now and not had any indication of the noise. I think I may have used the wrong spec gear oil when I last changed it. When I changed my lower unit oil last I used cheap Pennzoil 80wt gear oil that I got at the local general store. I drained that out and used some good stuff I bought at Bass Pro, Mystik 90wt I believe. Could have sworn the noise was from my top end but you know how noises can travel. Maybe that oil was not the right spec? Anyway, since changing that oil I haven't been able to recreate the sound. When I bought the boat I never changed the gear oil from the original owner and it made that noise too. Probably had the wrong oil in it from the original owner.
