Cummins QSL9

[drmnj]

Does anyone out there know of a good Cummins Disel course that I can take to learn how to maintain, trouble shoot & repair if necessary my Cummins QSL 9 engine?
Thanks in advance for your suggestions

Same answer, go to the the boatdiesel.com archives. You can read for days about Cummins and find a few good men in FL to talk with about service and care of your QSL.
