Would appreciate anyone that can confirm the correct color of the wires for the coils. Green/white and green/yellow. Which is for the top cylinder and which is for the bottom. Serial number og683980 [1998?]

Re: Mercury 20 hp coil wire colors

Thank you. That is what I thought by comparing older models and there color coding. A friend said this motor ran ok for three tanks worth of fuel and then wouldn't run anymore. I noticed that there were new plugs installed and suspected that the spark leads were on the wrong plugs. Would you happen to know the correct gap for the plugs. NGK BP8H-N-10
