Hi Al,
I think you're right. I went to the boat yesterday intending to pull the prop shaft out of the coupling so I isolate the noise to the engine. But it didn't slip out easily. So instead I opened up the reversing gear and rotated the shaft by hand, in neutral of course. I had my wife take a couple videos for the sound. It's a little difficult to tell, but between what I could hear and feel, I think the output bearing is bad. I don't know how much of the noise is due to other rotating parts in there. I'll have to read up on replacing it. It's probably just a bearing and a seal? Offhand it looks like I can do this with the motor in the boat, but hoping I don't have to take the whole reversing gear out. Wishful thinking?
Here are the videos. Let me know what you think.
