I have a 1978 Evinrude 115hp and need to replace the lower unit. I was wondering what was compatible. It has a 20 inch shaft and the model number is 115 899C. I think it is compatable with all Johns\Evinru 4cly up to 1991 but I'm not sure. Can someone help me with this.

I think there is a conversion chart in the "Top Secret File".
