New Coupler Style For Mercruiser ALpha I??

[kdmiller8251]

Moving along on repairs. I got the engine out so I am looking at replacing coupler. The coupler I have is a triangle with 3 bolts. I have a 1990 mercruiser 5.7 Serial 0c664556 with an Alpha I 0A827029. From What I can tell there is a new style coupler out there. One has a yoke the other does not. Which one do I get??

Thanks

If you get the one with the yoke, it also has grease zirks on the coupler and an extra oring on the yoke to keep the grease in the coupler.
It's a newer and better style.

Don:

can I still use my old yoke on the new style coupler?

Sure, it just won't hold the gease in the coupler as well.
