      Where is the year stamped on a Rotax cylinder and case?

      Does engine need to be taken apart to see it?

      The cylinder MY is cast on the right side on the intake.  Its a two digit number inside a circle.

      The main case has a serial number stamped on the right side just ahead of the clutch fly wheel (on a smooth flat area).  You’ll need to reference this serial number with a Rotax agent to identify the MY of the casing.
