    Alpha 1 Gen 1

    How old is old? Why are you wanting to change the drive? Regardless of the age, If it will not go beyond 2500 rpms without issue, changing the prop or the drive will not solve what ever is your problem.

    Alpha 1 Gen 1

    Found this for everyone's future reference: Beginning in 1983 Mercruiser introduced the R/MR/Alpha 1 series of sterndrive models. These units differed greatly from previous years not only in design but also in that the flywheel housing on the engine changed at this point. This creates one of...

    You have new style center rise manifolds. You say risers, Risers are spacers between manifold and ELBOW. Is this what you have? Many people use conflicting descriptions. A manifold is a manifold.

    Alpha 1 Gen 1

    One other question, 1989/1990 is when merc went from Gen 1 to Gen 2 for Alpha. Gen 2 use a different input shaft and have 4 nuts and bolts, 2 per side, visable.

    Mysterious Milky Oil - Not Risers...

    There are a few ways to test. If this is isolated based on your images to one cylinder then as suggested it could be a hole or possibly a bad head gasket on that cylinder. First I would perform a compression test or leak down test which might reveal a bad head gasket if that is the root cause...
