Item Details
  • Excellent Shape
  • This the newer style engine coupling assembly used on MerCruiser GM 120hp 2.5L / 140hp 3.0L 4cyl models (Serial 0A000000-0F000000) but more so 1983-1997 that had this particular style coupler AND 12-3/4" flywheel. They were seen most frequently during this time period in different iterations. (12632A3 / 12632A6 / 12632A7)
    • Early Style 12632A3 (Did not have extended greaseable tube for yoke splines)
    • Later Style 12632A7 (Had extended greaseable tube) - THE ONE BEING SOLD HERE
  • Splines are in excellent shape.
  • Just make sure your coupler looks similar to this (Triangular Style) and is not the round style that bolts to the crankshaft studs.
  • These were intended to be used on the 12-3/4" diameter flywheels not the larger 14" flywheels (Found on 1998 & later models)
    • Measurement between the holes is 10" center-to-center
  • Purchase with confidence!
