Type C Gear oil

[Evinrude Boater]

I thought Type C was for electric shift gear cases from the 60s. Can it also be used in mechanical shift gear cases? How is Type C different?

it is thinner, use 80-90 lower unit oil.

In the 60's manual shift lower units called for Hypoid 90 gear oil and electric shift called for Hypoid 80C. As has already been stated, the 80C is a thinner oil. I'm not sure what the "C" classification means.
