Item Details & Compatibility

  • This is a complete Yoke Assembly for  Alpha One Gen I Sterndrives (1983-1990)
  • Alpha One Gen II (1991-1997) {SN OK999999 & Below}
  • This one has three o-ring grooves but will work fine replacing ones with 2-grooves on Yoke
  • Also this would be compatible with 1971-1982 V8 305 / 350 Stern Drives only because of  the measurement of the yoke.
    • 1970-1982 MC-1 & R Drives on Inline engines used a shorter yoke which is not the one available here.
  • The same yoke / U-Joint assembly was used in the years described above regardless of engine / gear ratio of outdrive.
    • I.E. 120hp 2.5L / 140hp 3.0L / 165hp 4.1L, 470 / 165hp 3.7L 4cyl / 4.3L V6 / 305 5.0L V8 / 350 5.0L V8 / also the very rare instances of alpha ones paired with 454's
      • However take special note of the yoke length as described below.
  • The Yoke on this measures 9-9/16”
  • Make sure that yours measures the same as if you have an inline (4 or 6 cyl engine pre-1983) it is likely that your yoke is the short model that measures 8-1/8” These are not interchangeable.
