Only one prop is STC'd for the O-200 conversion... the McCauley 1A101/DCM 6948.  Others must be field approved (this is what it reads on the STC).  The STC paperwork also states that after initial break in, a 6950 would be better... but still, you would need field approval.   This is for my O-200-A powered 'coupe with EAA AutoGas STC... The following four lines are my estimates from last 20 hours of flight recorded (I keep a journey logbook)... 100 mph ground speed average (75% power) 5.9 gph (75% power - no leaning below 5000') 350 fpm climb at 1000' / 100° F / 1400 lbs 750 fpm climb at 1000' /  65° F / 1300 lbs   Power Plant Operating Limitations 1.  Engine: Engine Make – Continental Engine Model – O-200-A Rated Power – 100 HP at 2750 R.P.M.
