Evinrude 9.9 2 Stroke Model Number? Can Anyone Tell Me How To Find It

I have looked at transom mountand I find 13G02 under those are the numbers 188149

When I took the cowl cover off there is a silver plug that has the number R8525872

On the shaft it has 330507D2

I went to the evinrude parts site and none of those numbers match up in a search for model number.

It says on the help page that it's mostl letters . There is nothing more I could find on the motor.

Looked at it with a flashlight and cleaned it up. I bought it used and the guy said he wasn't sure of the year.

He said it might be an 1989

I'm trying to buy an owners manual and a few parts for it.

Any help would be greatly appreciated.

Thanks Jim
