As example
Upper gears 19/16 = 1.187
Lower gears 15/19 = 0.789

Calculation 1.187/0.789 = 1.504 ratio

So rotate and count
1.26 lower 17/18 = 0.944 10X = 9.44
1.35 lower 15/17 = 0.882 10X = 8.82
1.50 lower 15/19 = 0.789 10X = 7.89
Thank You! That worked, I rotated the vertical shaft 10 times, prop shaft turned a bit more than 8 3/4, I’ll call that 8.82. So it is what it was a few years back when I checked it all together, 1.35. ( I just got new lower gears 13 hours ago) thought maybe someone put the wrong ones in.

Damn, that sucks but at least you got it out and you know what happened. Wow. Glad you got it resolved.

That sucks. I broke a tooth off the gear set and locked up the drive. Where your splines are twisted on the short shaft, mine sheared of clean off. It didn't damage the case though. I have an extra long shaft if you need one. Man, I don't miss I/O's.

Wow, you twisted on both ends. I forget, was the motor free to spin or locked up?

Sorry, I meant could you turn the engine over when the shaft was still in?
