The range of prop RPM should be the same in both a geared
Mazda and a direct drive AC engine. Unless of course you are cruising
the Mazda at way less than 50% power. I think something else was going
on with your AC pump failure situation.

Eh?  What's prop RPM got to do with it?  The speed of the pump is directly
proportional to the speed of the engine.  I think that Ed just couldn't find the
proper pulleys to get the proper ratio; he needed something between the "too fast
at max" and the "too slow at idle" pulleys.

Russell, "range of prop RPM has everything to do with it :-) I know
you are very very bright so think about it and re-read Ed's message :-)
No offense intended. Ed also did not mention a pressure regulator.
