200 hp lower units

[rolrandy]

I have a 1994 200 and a 1999 ox66 lower units, are the gear ratios the same in those 2 and in all 25" lower units?

Bump
are gear ratios different for other hp's 150 vs 200
maybe I have 2 different hp lower units ?
I guess I could count prop rotations on the one thats out now
what gear ratio should they be?

What gear ratios did Yami put in their lower units? 150-250 hp range?

ProV 150s had 2:1, most 200s 1.86, Excel 225s 1.80 for some reason.
