my alpha 1 gen 2 was removed and separated for repairs. Removed shift shaft busing and replaced with new. Removed and reinserted shift shaft. replaced various seals. Replaced impeller. Connected upper and lower unit, filled with gear oil. Installed on boat and now have no reverse. removed checked position of everything and same results. Could I have messed up when I re-inserted the shift shaft into the bushing. How do I confirm and find problem.
