I am going to look at a used 1996 Maxum with a Mercruiser 3.0 /Alpha 1 on it. A mechanic checked it out and noted a grainy sound. I saw the boat a couple weeks ago and it did not look abused at all. The same mechanic said the engine sounds great, oil is clean and compression fine. I estimated $250 to replace the gimble but could I be in for more than that?
