Re: calculating the age of my johnson 9.9

INTRODUCES

I=1
N=2
etc.

CU = 87 D=production run (usually several per year)

In '87 the carbs, and exhaust tubes were different. So were some other things, of which I don't have a full listing. Impellers are the same. Now that you know your model year do an e-bay search for an OEM service manual. It'll have all the instructions for your impeller replacement complete with pictures and all.

Thanks for your help ! By chance do you happen to know what the Electric on back of the engine cover refers to ?
