Xinrong U-Joint Bellows Fits Mercruiser Alpha One, R, MR and Some #1 Replaces 60932A4，for outdrive

This is what you need for the alpha 1 gen 1 it fastens over the outside with a hose clamp in the drive and the transom unlike alpha1 gen 2 the bellows are different at the gimball and go inside the port on the drive then a special tool used to insert a retaining ring ......gen 1 is so much easier :)
