Hi,
I have had this bearing noise in the middle section for such a long time that needs extra care now.
I was thinking that it was coming from the the lower bearing in the crankshaft but i diagnosed that the bearing is fine. The power head makes a little bit of bearing noise but not that significant to be honest. (it is a 25 yo outboard)
So I removed the leg and started to check if it was coming from the driveshaft bearing.

Here is the bearing noise from the leg:

It sounds the same as the noise from the middle section. Which means the noise may travel travel through the drive shaft. (there is no bearing in the middle section)
What are you thoughts? Has anyone had this issue before? Easy fix? Would I need to remove the entire driveshaft to locate the upper bearing or I can get away just by removing the nut?
Would require new bearings and seals I guess and lots of elbow grease.
