I have a 1987 90 hp johnson. Always started and ran fine until Thurs this week- seemed to have a loss of power. Pulled the cover off, and one of the spark plug wires was not connecting properly.
Fixed, and tried to start, and started and ran rough a couple of times, and died.
Now, will not start at all. I have no spark in any of the cylinders- pulled the boat out, and checked with new plugs. Not one has spark out of 4. You would think that if one power pack was bad, the other would fire. Is this true? What else could cause this? My manual says to disconnect the one pin circut stop connector- I will try this, but anything else?

oh yeah, my battery grouned out overnight, apparently, against my aluminum boat, and killed the battery. Could this do something?
Just need to know if I need two power packs, or how to test the ones I do have. seems strange that all 4 cylinders are dead, with no spark. Please offer any suggestions you can!!!

Hey, yes, I thought of that, and had my son push the button on the remote instead of using the plastic thing- still the same thing- no spark. thanks for the response...does it make sense to you that there is NO SPARK at all, and two power packs. I will try disconnecting the stop circuit, and see if that helps. Please let me know if you have any more thought on this- I am desperate, and don't want to spend 200 bucks on power packs if is uneccessary!!!
Thanks so much
