Was wondering since I've never been inside a lower unit, is changing the seals something that can be done without much outboard experience. I'm pretty decent with my hands. I do 99% of my automotive repairs myself, since that's what I went to school for yrs ago. But I don't want to open up this lower unit and have something fall out. If I didn't see where it came from, I'll have no clue where or how it goes back in. Thanks for any help you may offer.
