We have a 2002 480 CPMY with QSM 11s and ZF 325 Trans. At 1900+ rpm our starboard engine (presumably the trans) grumbles something serious. At > 1895 rpm, nothing happens and we can cruise for hours. Cummins says the motors are fine and that the trans oild seems fine. I do loose a bit of power and it does seem like we slip when it happnes. Any ideas?
