What would you do next? I've had a slight engine vibration over the last 6 months and can't seem to resolve. 2006 Twin engine boat (Fleming 55), engine hours around 4500. We have...1) Dove on props and running gear, had divers check props and running gear, had boat pulled and had mechanics and surveyor check props and running gear, tuned the propellors, had 1000 hours service performed, 2 fuel injectors replaced, ran oil tests on transmission, and engine, switched the balancing weight from one engine to the other (not sure what this was called) all performed by former direct Cummins mechanic. He also assessed engine mounts and following that sort of put up his hands.
Should I just leave it and cross my fingers? Anyone have a similar issue and found resolution?
