Lower unit is off and all were disassembled, cleaned and reassembled properly. Halves seat properly without contents.
I purchased two FD-12’s and have been picking over each for parts. So maybe the mix -and-match is causing the problem although, I have measured key parts with micrometer and they are very close and wouldn’t stack-up to cause the issue I have described. The bushing locating pin is gone so nothing in the way of the bearing assembly seating properly. I still have to find a solution to that issue.
I will keep working on it.
Whoa, you know that the skeg and upper gearcase are matched and not interchangeable with each other, right?
