Hello All
I have a 1978 Johnson 70 hp
Model is 70EL78C
Serial is J4934075

The question I have is there anyone out there know the wiring for this motor. I would like to hook a key switch, kill switch and a tach if it is possible. What is the WOT RPM For this motor.

Thank you for your time

What do you mean know the wiring, is a wiring diagram what you're after?? A manual will pay for itself when servicing an outboard motor. Try ebay or any other of the numerous sources constantly mentioned on this forum. You WOT rpm will be around 5200 to 5700, depending of course on your prop, boat and set up, etc...
