    Water in oil, could this be the issue?

    because Sierra is generally Chinese junk. Mercruiser gets half of their manifolds from Buddy Barr castings. So you cannot go wrong with her Factory Mercruiser, or Barr castings. The gaskets that failed on you leading to water intrusion are known as Sierra green leakers.

    Water in oil, could this be the issue?

    Most likely its bad exhaust manifolds However if you had the plug in and water got as high as you say, your starter is now junk, or will fail very soon, and if the alternator was under water, that will fail too. So will any wire harness that was under. Doubtful water got in the crank case...
