Part Number(s) Included

  • Volvo Penta / OMC Joint Venture 3850935 3855695 Cobra SX Sterndrive Upper Gearcase Unit 
  • From a 4.3L GL 1994 Model
  • 17/27 Teeth For the Lower Gears (1.66 & 1.97 Ratios)

General Application / Compatibility

  • So 1.66 was stamped on the plate from the upper unit, but basically the uppers only came in 2 flavors and the lowers came in 5 flavors, 1.66 reflected the "overall" ratio after combining the upper & lower, hopefully this guide clears up any confusion.
  • Upper Unit Flavors (SX and DP-S):
    • 3857007 VP HSG AY,GEAR 22:23 (1.43, 1.51, 1.60, 1.66, 1.68, 1.78, 1.95)
    • 3857010 VP HSG AY,GEAR 21:26 (1.79, 1.89, 1.97, 2.18, 2.32)
  • Lower Unit Flavors (SX):
    • 3855692 VP G'CASE AY,SX 19:26 (1.43)
    • 3855693 VP G'CASE AY,SX 18:26 (1.51 and 1.79)
    • 3855694 VP G'CASE AY,SX 17:26 (1.60 and 1.89 )
    • 3855695 VP G'CASE AY,SX 17:27 (1.66 and 1.97 )
    • 3855696 VP G'CASE AY,SX 17:30 (2.18 only )
  • Basically this particular is one of the earliest iterations of an SX drive as this would be 1994... Allegedly pretty much anything from 1994-2006 would be the drive (SX-S / SX-C / SX-C1 / SX-C2 / SX-M) The SX-M was produced roughly 1998-2006 but most of the things were interchangeable with the earlier drives, especially when replacing as a whole unit.
