  • Used in MerCruiser MC-1, #1, "R Drive" lower units 1970-1977 but also could be used as a complete set in 1978-1982 units if you use all of the gears here.
  • (If your driveshaft HAS A PRELOAD PIN then these are the correct parts, if your's does NOT have a preload pin, then these are NOT the correct gears)
    • The time period 1970-1982 should be the time period that covers when the drives still had the preload pin, but the easiest way to identify what type of gears is whether or not there is a preload pin, and by physically looking at the gears you can see they have a different rotation.
