      July 12, 2020 at 5:05 am I have the exact same problem. Engines run great except between 820 and 950 rpm. In that fast idle range the port engine vibrates like crazy. Just replaces injectors, but that didnā€™t help. Mechanic thinks its the injection pump which we will have rebuilt. Can you provide an update on your issue? Was it in fact your pump? Are you all fixed now?

      April 30, 2020 at 11:28 am Hello all, i’m going through my new to me boat and found this tool inside the Cummins Marine bag. Does anyone recognize this? It could very well be that it’s not even related to the engines but figured i’d start here. Thank you, Chris
