1 A dealer can normally tell from the vin number.
2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement
info.
3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires.
4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.

50:1
50 to 1 ratio
Say 50 teeth divided by 5. That is a ten to one ratio.
A 1989 model, 70 hp Johnson outboard requires a 50:1 ratio, one pint of 2 cycle oil, to six gallons of fuel.
i think you would be in need of a huge gear box transmission ratio of 1:30
Sticker says 100:1 but they backed off that. 50:1 is right.
It is 50/1 = 50.
The ratio is 100/50 = 2/1.
The 1989 model, 125hp Force outboard, requires a 50:1 fuel, to 2 cycle oil mix.
It is 50/1.
