Have a 92 liberator with 454 and OMC outdrive. Today it was running fine at full throttle then suddenly a vibration showed up. At half throttle no vibration is felt and above the half throttle the vibration shows up and increases. Any ideas? I have checked the prop and that seems fine and is a new prop. The engine revs smoothly and there is 300 hrs on engine and drive. |

It sounds like you may have a bad gimbal bearing or u joint. |
