Sounds like your on the right track now Tubs.
Not sure what’s holding it from coming apart.
Perhaps just gasket cement?
Perhaps the clutch spring needs to be "unwound" off the drum
by holding the prop shaft and spinning the driveshaft backwords?
Then there’s always the bolt holding the pinion gear on the end
of the driveshaft….. probably not that, but just a thought.
I was just putting together a Gale 5D10 lower unit off an Atlas today.
Not sure how similar the Martin may be.
Hope to hear and see more on your progress in case I ever tear my
TS 75 apart!
