Item Details

  • Used from 1972-1989 on virtually all OMC & Mercruiser 3.0L 140hp power plants. (both companies used the same GM blocks, but OMC used bolts rather than studs at the end of the crankshaft to hold the couplers on)
    • This is for engines with a 2-piece rear main seal....which is what they used before 1990...
  • MerCruiser Part Number 423-3816
  • GM part # N9341352 / 9341352 (Stamped / Cast)
    • Equivalent GM Part numbers (Other common Stamps
      • N9341352 / 9341352
      • N398776 / 398776
      • N393775 / 393775
      • Sometimes looks like 393776
  • Yours should looks just like this.
  • Engine turned over by hand freely before removed.
  • Possibly some surface rust on this in some areas of the cast part (visible in pictures) but this is a very nice crankshaft & I don't think you will be disappointed.
  • If you are unsure if this will work for you, just ask.
  • Purchase with confidence!
