Ernest,
If it turns counter clockwise it's the 2.17 ( you don't add the one in the
calculations).
If it turns clockwise it's 3.17.
The 2.17 turns counter clockwise.
The 2.85 turns clockwise ( looking at it from the pilots seat)

George, if you meant to confuse me then you have done a spectacular job 8*)
Let's back up just a second. The ring gear is locked. The output is taken from a splined shaft that is driven by the planet gear carrier. When I turn the sun gear clockwise, the output shaft turns clockwise. It takes *about* 3 turns of the sun gear to get one turn on the output shaft. You've said (or at least I read it that way) that this is both a 2.85 and 3.17. Was there a typo in there somewhere?
Kelly, I was thinking more along the lines of 8000RPM redline, with a 7000 cruise. That would put the prop revs at 2208, which I *think* is a good number. The problem I'm having is trusting the 3-pinion planet set I have. I took the gearbox to a transmission shop. The technician said I was wasting money to replace it. They use that same gearset to drive busses. But I can't help but to be swayed by advertisements like item number #9X on this site:

That's a lot of reassurance for $218 that follows all the laws of physics I know. I would have switched it out already, I'm just not positive about which gearset I have exactly. Does anyone know for certain the teeth count on the different gearsets?
