Yeah, I don’t see 10522C in the 1975 9.9 listings, but was only looking in Marineengine.com
There were no extra long models (25″) offered in 1975, so it refers to either a 15 or 20″ length 9.9.
So, guess you need to have another look at the ID plate.
The “C” is just a designation of some sort of change during the 1975 model run, would be hard to figure out just what that was just looking at the parts book….Could be something as simple as a wire clamp though, so may be insignificant.
I know there was some sort of parts change in the gearcase around this time though.
Tell us why you are concerned about this model ID, are you looking for a specific part, or parts change?
