replaced one of two coils on my 35 hp johnson last summer. Cranked the boat up two months ago and it ran fine. Went to crank it yesterday and I have no fire on either plug. Im thinking CDI box??? changed both plugs and if I had another bad coil it would still run on one cyl. Checked all my wires, actually rewired it two years ago. Checked all connections and the safety switch. Any other suggestions.
Thanks for any help.

Look to see if the stator under the flywheel is oozing. Nuetral switch in the control ok ?

OMC put two kinds of ignition on that era of 35"s. Post the Model number so that we can get to the right ignition style.

Model is 35EL79A. Checked all wires and fuses again today, wire continuity and all connections, changed plugs, checked all grounds, still no fire on either plug. Thanks,
Ken

Bump... for Mike to see it.

Thanks Old Frog. But I still ran into a deleima. Even with the model #, they still show both ignitions. So I am going to base this on the fact that it is Factory electric start and not add on electric start. Which in that case the motor uses a combination Stator/trigger assy all built into one unit. I would highly doubt that style would be at fault. So my first suggestion is to replace the CDI-switch box-ignition module (whatever you want to call it) after testing the voltage output on the brown wire and brown/yellow stripe wire. You do this by pulling those two wires out of the plug-in termial and hook an OHM meter to them. Then crank the engine and look for voltage. That voltage supplies power to the ign box. If you have voltage. Most likely it is the ign box....about $90. It cannot be the emergency kill switch unless the motor is remote control and then the control box would be of later ora as the early units did not come with a kill switch.

Mike, thanks for the info. I went ahead and purchased a new CDI box and will put it on today. Will post back and let yall know what happens.
