Thanks Tubs I found it on you tube . Not too complicated. Question do you think it needs two newer Omc coils or would one suffice? Solder the spark wires to the one coil? Don’t know the voltage of the old vs. new? Probably not enough. Did you experiment?

Plug wire end to plug wire end test assumes there are no breaks in either wire or bad connection wire to coil.

Stanley so when connecting primary coil to ohm meter (wire to points and copper ground wire) I have continuity. When connecting ohm meter to both spark plug terminals at the coil …nothing. So assuming secondary is bad.

Also Tubs, which newer omc coil part# number did you use?

[garry-in-michigan]

Both plugs on the same wire will fire the plug with the least resistance. You get the same results by grounding one of the apposed twins wires and jumping the two plugs together. It will run on one cylinder. The cylinder with the lowest compression or the smallest gap in the plug electrodes. It is very difficult to get them exactly the same.

Yup that makes sense Gary thanks. Any recommendations on which coil to use?
