Johnson 60 HP

Hi, I have 1987 Johnson 60 HP outboard no spark on all 3 spark plugs. Any help would be nice. Thanks

Try disconnecting the back wire with yellow stripe that feeds into the powerpack, thats the kill circuit

Ok I will try that thanks.

I tried that and still no spark on all 3 spark plugs. Any more suggestions? Thanks

you will need to run the tests for your motor outlined in this link

Remember that the starter needs to be turning the motor well to produce spark, a tired battery will mean no spark. I normally check by removing the sparkplugs so the engine turns faster

It's unlikely all 3 coils failed at once, so you will be checking the stator, and timer base first. The CDI guide Bonsun mentions will have you check the cranking output of both devices. You will need a special "peak-reading" voltmeter to check the output. If both of these devices check ok, then it's likely the power pack. Engine to crank at least 250 rpm's to make proper ignition voltage output.
