Earlier in the season, I was running the engine of my 320 in gear at the dock at about 1,500 rpm. All was normal until I heard a noisy mechanical sound. There seemed to be a vibration from somewhere and the engine nearly stalled. As soon as I put the gear shift into neutral, the problem and the noise stopped. It has not happened since. It is a Hurst transmission on a Perkins 30. Any ideas ?
