I recently saw this video that uses a cutaway to show how an outboard lower unit works. This is from Boats.net, which is where I buy stuff I need for routine maintenance.
Anyway, having the cutaway really helped me understand how these things work. I still wouldn't want to tackle rebuilding a lower unit myself, but at least I now have a better understanding.
Here is the link to the video on Youtube:
