1983 Evinrude wire locating.

Anyone know if this motor has an rpm wire for a gauge and a temperature gauge wire?
The temp sensor goes to the alarm, I don't know if the signal will work a gauge I install.
It shows it to be a tan wire from the temp sensor.
I don't know about the rpm or what color the wire is if it has one or can I add a wire and where.

Generally temp gauge senders and overheat alarm switches are different. You might look on the crowleymarne site and see what your motor came with, likely overheat alarm switch.

Check the head and see if there is a brass plug you can remove and screw in a temp gauge sensor.

BTW- a water pressure gauge is a much better indicator of engine cooling.

I believe it has an overheat alarm switch it's in the head about the centered on the edge on each side. I haven't seen anything that looks like I can remove to put in the sensor that came with the gauge.
