52DA Prop pitch with Cummins QSM11

[Keith Grayson]

Has anyone with a 52DA with Cummins QSM11's reduced prop pitch to extend the exhaust and turbo life of their engines and if so what pitch? Both sets of props came from the factory and are EQY 28x35. Apparently they overload the engines throughout the moderate cruise power range.

Search the 480 Sedan mage, and the 500/52 sedan pages. These have been discussed at length. I don't know how to show you particular threads, but it's here. Short answer, yes. A lot of props have been reduced based on the advice on
www.sbmar.com and read "Tony's tips" He's been called the expert on Cummins dry exhaust trouble. Mike
