Mark the housing and prop shaft with a paint stick or the likes.
Do the same on the input shaft.
Turn the input shaft 1-2 times in order to get the prop shaft marks to line up. Now see where that puts the marks on the top/input shaft.
If you have turned the input shaft over 1.5 times to line up the marks on the bottom, you have a 1.5:1.

Here is a link to available gear ratios. Alphas are at the bottom of the chart.
