QSB 380 Cummins

[buddymac]

I have twin QSB 380's in our 2004 Sundancer 390. When started up for the first time today, there was a loud squealing sound from the port side, sounded like a belt. I guested something was seized.I went into bilge with a light and fired up engine again to see what was stuck, but it fired up and all was ok. Any advice or thoughts on this? Next visit, I will pull belts off to see if everything turns freely.

I remember reading something on boatdiesel.com with some having a bad tensioner. You have only one belt, so it should be easy enough to isolate.
