It was really simple and easy to secure the harness to the original bolds with a zip tie.

Thanks for sharing, I have a mercury 850 with coils and the wire harness is an absolute mess. The owner before me look like he used liquid tape to cover over all the warning. I have a second motor that was on the boat but the distributor cap went bad and finding one is not easy. So I decided to switch the motor and went to fire it up and was not good spark. 5 volts to the coil. Closer look the wires to and from the stator were completely corroded

Thanks for this! Great idea with the zip-tie too.
What is that red or orange component that your solenoid is mounted on? I'm restoring a Frankenstein 50HP merc that has a 1973 upper and lower unit and the engine looks like a 65-67.. some parts are missing and I've seen that part on a few of these old mercs and wondering what it is.

I need a wire harness for a 63 mercury 650 do you know where I can find one?

@EastTnDixieOutdoorsman says:

Can you give a video showing where exactly each wire went. I can understand the directions from jet unit but I understand better when I can see the parts named 1st hand and trace where each wire goes. If not I understand. Worth a shot.
