MerCruiser Alpha One R/MR 59830A1 U-Joint Yoke Outdrive Upper 83-90 Stern Drive
****THIS IS A STOCK PHOTO YOU WILL RECEIVE A UNIT IN THE SAME CONDITION AS THE ONE PICTURED HERE****
Item Details & Compatibility
- This is a Yoke Assembly for alpha one R / MR / Alpha One Gen I (1983-1990)
- Also this would be compatible with 1971-1982 V8 305 / 350 Stern Drives that required the longer edition yoke (4cyl & 6cyl engines from that time 71'-82' used what was called a "short yoke")
-
The yoke style 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.
- 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
- The Yoke on this measures 9-9/16” (actual yoke part, you can see the full length in the picture)
- 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.
- One other thing to take note is that MerCruiser added the extra o-ring around the middle of the yoke at some point in the late 80’s, however this shaft is still compatible in all of those systems as that o-ring was not imperative of function
