'Can some Ranger engine wizard possibly tell me the Engine to RPM gauge drive ratio of a 200hp ranger 6-440-C5 engine?
I am having the old Jaeger C-11 RPM gauge overhauled and the shop wants to know this for the calibration.
Many thanks

'Per the type certificate(and other manuals) the tach output is 0.5 times the
crankshaft speed.
