I have a 1988 - 1991 30HP evinrude. No model number, but it is a short shaft with electric start. If I want to add a Tach to the setup what to I need to add. Currently, I have a side binacle with key. Here is a photo of the binacle, I will try to get a better one tonight along with possible model number.
