Omc nitro lower unit question

[Sam-t]

Hello everybody, I have a question regarding my short shaft 70hp Johnson with a nitro gear case, does anybody know the specs on where to adjust the shift rod to? It is a 15” 56ci

I don't think a nitro lower ever came on a 56ci motor except SST 60 but shift rod height on 15' motors was 16-13/32 plus or minus 1/32
Hope this helps
Enjoy life Keith

No they didn't but if you use the base plate, power head and exhaust off a 56 cube, it will mount right on a short shaft Stinger with a few small mods. The 86-87s has the same crank spline as a Nitro gear case.

If I remember correctly, the base plate from the 56 is 1/4" thicker, unless it was moded or if its a custom plate. Keep this in mind if you use the measurement Keith gave you.

What’s the issue you’re having?
Can’t get enough travel to get F-N-R?

Hey all, sorry for the late reply, thanks for the help. I got it on and everything working right, now just wait for the ice to melt to get out for some testing

Sorry for all of the questions I’m new to the 70 stuff, does anyone know what thrust washer i should use with a cleaver prop on the nitro lower?

[sharpeye Mike]

Not sure about your question but I use what ever works. As for keeping that Nitro healthy, I don't shift mine while the motor is running, at least when running a solid hub prop.
