MTboatguy - I pulled the cover off the back of the out-drive, and underneath there is an inspection plate. I removed it, and everything looked clear as far as I could see. I haven't removed the out-drive yet. As a kid I used to work on Chevys a bit, mostly due to abject poverty, so I'm comfortable working on the engine. I'm frankly a bit intimidated by the out-drive... Never had one off, and not sure what's under there once it comes off. In my feeble mind, I always imagine pulling it off and having loaded springs, bearing and unidentified parts scattering across the concrete never to be seen again. Do you think that's where my problem is?
