Good day all,
So, removed the lower unit to replace lower shift cable, while it was off I split the lower unit for some skeg repairs, I can't get the drive spline to line up, due to the vertical drive shaft on the lower not budging. Prop shaft will spin, can shift into fwd,neutral,rev, and the prop will catch the clutch for all gears, but will not move that drive shaft at all maybe 1/8th inch. The boat ran prior to the repair.

Ayuh,...... Welcome Aboard,...... Probably because of the resistance from the impeller,....

Took the impeller out, pour some gear lube down from the top end to see if anything was just dry. Still no movement, I can get about a 1/8th" back and forth that is all.

oil based products will destroy rubber.
If you removed the impeller and it still wont turn the lower unit is damaged
