Pull off the diff cover and count the ring gear teeth and the pinion gear teeth, then divide the pinion gear into the ring gear. That will give you the exact ratio.

most differentials have it stamped on the housing but that relys on trusting that the center has never changed you can also try turning the prop/tailshaft and counting how many turns of the shaft to 1 turn of the hub it is not as acurate but it will give you an approximate idea.
