C90 Yammi help

[duknut1975]

I understand that the C stands for C series, but what does that mean compared to the same model year without the C?

Also, what does the "Pro" mean on the smaller outboards? I am looking at a 60hp 93' that is a Pro?

The pro series have a bigger gear case.

My motor is a C90 and my understanding is that the "C" stands for commercial, which may have meant without oil injection. Just a darn good, basic motor. Good Luck!
