MerCruiser Alpha One U-Joint Assembly Yoke 814819A2 3 Upper Unit Gen II 3-Groove

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.
