Yeah, I believe it's APG 90 (hypoid 90) for mechanical shift and 80 for electric.

The 1968 OMC Stern Drive Service Manual says "Fill upper and lower gearcases with OMC Type C Lubricant." Gotta love the manual...

A quick Google gives: this. (http://forums.iboats.com/showthread.php?t=87550)

I really need to read entire posts!!!!!!!!!!!!!!!! But below is my wordy answer:pimp:

The electric shift stuff is a fair bit thinner so the clutch springs can grab, it is Premium Blend C. If you put 80/90 it will slip like crazy and blue the clutch springs if run to long, when I say to long about two miles!!!! See if your suppliers can get you the right stuff, it will save you from killing the guts!!!
