    Make sure the shut down lever is fully seated.

    Just curious if fuel supply has been checked? Are filters clean, lines unobstructed and pick up tubes clean? Perhaps try running on a different tank. Are all valves fully open?

    Fuel system was checked, filters changed and only single tank. Port engine runs great

    Hows the bottom and running gear? Reading over the scant information it sounds like the boat has been sitting unused for awhile?

    Any clues as to what was shaking? Engine? Trans? Shaft wobble? What rpm was it shaking? How clean is the prop? Long shot but you could have picked up a rope or debris on the seatrial.

    Given the limited info, I'd probably dive the prop to check the simplest, most likely source of vibration first (we regularly pickup stuff on the prop, like almost every trip).

    Next I'd check shaft wobble, bent shaft would demonstrate bad vibrations.

    High idle at the dock again to rule out the engine as source of vibration.

    Once you eliminate those the trans is the next order of bidness and that's above my pay grade.
