Re: Need help with 1968 evinrude 40HP selectric shift
So when you punch the forward button it does nothing, punch the neutral button it does nothing, and you punch the reverse button it goes in reverse, or is it in reverse no matter what you do? In any case you will have to troubleshoot it from the control down to the engine. 12 volts on the green shift wire = forward, no voltage on either the green or blue shift wire = neutral. 12 V on the blue shift wire = reverse. At no time should there be 12V on both the green and blue shift wires at the same time.
Electric shift gearcases use Type C gear oil, not the regular 85-90W stuff.
