I am contemplating the purchase of an 1987 Searay with an OMC Cobra sterndrive package. The only OMC I have ever owned was a Johnson OB, great motor. I have owned 3 mercruiser packages and would prefer one, but this boat is what I would like--except for the OMC part. The local Searay dealer told me he would have no problem buying a used OMC and that parts are still avaialable. The boat is FS by a private party, dealer has no gain in the deal. Any comments?
