Item Details

  • The gears are For All V8 applications for Pre-Alpha/R/MR/ALPHA ONE Gen 1, so 1970-1990 as a general rule.
  • (You may need to replace the bearing on top of the shaft depending on whether you have a 1970-1982 vs 1982 & Up application as they each used different bearing sizes)
      • ...These were also used on Gen II drives 1991-1997 but you would have to swap out the shafts and bearings...
  • The gear set here is MerCruiser 43-59831 & 43-59832 > 43-59832A2 
  • This set supersedes to 43-18410 / 43-18411-1 > 43-18411A2 (Also Equivalent to Sierra 18-2202)
    • 20-22 (tooth count) 1.50:1 / 1.47:1 Ratio for V8 GM Chevy 5.0L 305 & 5.7L 350 sterndrive engines. (Early Ford as well)
    • Driveshaft and other bearings still installed on this.
  • If you have any questions on compatibility, or any other questions about this item, please don't hesitate to contact me.
  • The existing bearings are probably fine, but please inspect bearings beforehand to make sure they are to your liking as your races may be different than the bearings here, its always recommended to start with fresh bearings & races when performing this type of service work, but this is ultimately up to your discretion.
  • Freshwater Used Parts.
  • These look great and were removed from a completely functional upper gearcase.
  • Purchase with confidence!
