Someone may correct me, but I believe the frame/motor mount design has changed at least three times since 09. 10-11', 12'-17' (may be a change somewhere in this time period as well) and the newest design 18'-present (rieju).
I would start cross referencing parts and see what can be used from the '09 motor. You could use the 09 as a donor motor, which may help with costs and downtime for the rebuild on the '18.
