C90 prop combination

Some where I saw a chart with all the models/engine combos/prop choices, and can't locate it again. I am looking at a D with a 0-200, and
had noticed that the 0200 has a shorter prop (69") than others and higher RPM's. Anyone know where that chart is? I would like to better
know the sizesRPM's for the 0-200 in the, climb; cruise selection. Thanks

Mechanical tachs are not accurate. Buy or borrow an optical tach to get true RPM. I do not think it is over revving . Do not change your prop until you know your actual RPM. Check your airspeed indicator with a GPS. The are often inaccurate also.

I've got a 71/48 on mine but constantly get into an over-rev situation for cruise which for me seems a bit slow at 93MPH at 2350. Wondering what you are seeing for performance during climb and cruise and what you decided to do. I have an opportunity to re-pitch here in Poland during the winter.
Cheers

mine has a McCauley 71/48, just was wondering what others were running.

The 7153 is a 1A105/SCM. The 1B90CM or CF should be a 7148 for best performance.
