2002 480 properly pitched prop

[Dewbert]

Recently bought a 2002 480 sedan bridge with QSM11’s. I understand that the QSM 11 have an issue due to the dry turbos and you can de pitch the prop to help with this. I understand I’ll lose speed but what props should I run to help try to mitigate the dry turbo exhaust manifold issue? my current props are 28r 32.

I have Cats and cannot help you with the Cummins setup. There are a lot of posts regarding props and re-pitching the props under the 480 Sedan Bridge thread. My two cents are this; Unless you are running full throttle a lot, I would not change the pitch. Sea Ray set up the boat when new and the 480's are still plugging along fine.
