I have a 1987 mariner 50, 3 cl. I just replaced three ignition coils. Now, I need to know what plugs go where. The plugs position on the back of the motor is 1,2,3 from top to bottom. The coils are also top to bottom. Any help would be appreciated.

I did the same thing 70 years ago.
Always take pictures, make drawings, put ADHESIVE LABELS on electrical connections, piping. Good luck

Usually the top coil goes to top cylinder...

Maxrules likely has a wiring diagram for your motor. Compare the colors of the wires to the coils with the diagram and make sure they match. Also, compare the wire colors on the switchbox to the diagram to make sure no one got creative.

The switch box may have each terminal identified as to where the wires need to go.!
