Thanks for all of the advice. Thankful I asked rather than guessing.
And Fleetwin, I appreciate the warnings. I didn’t crack open the gearcase thinking it was going to be easy, but it is something that I want to learn. I’ve got a lot of experience rebuilding engines and transmissions on four wheelers, dirt bikes, etc. so I understand the importance of the seemingly unimportant and easily overlooked steps of reassembly. I’m just new to outboards (as all are at some point), but am extremely interested in learning because I love the mechanics of what makes them tick.
Evan, your desire to learn will take you far in this hobby. The learning never ends if you choose to pursue it. This is rewarding hobby and making mistakes along the way is part of the process.
