I was having a similar problem a month or so ago with my 1985 150 Johnson. After a new ignition switch i still had the same problem. Turned out it was a combo of; a wire getting smashed between the two halves of the control box and a red wire that was not making contact in the connector for the remote control. I moved my ignition switch to the dash and jumped the red wire around the connector and haven't had any problem since.

I disconnected the shift switch, cranked it still had no spark on port side. Jasoncoopercola I have looked at all my wires and have fixed a bunch of pinched wires, I was in the control box quite a bit, all is good in there. I think it's on to testing the powerpack and the stator, but i need a peak voltage reading DVA which I do not have.

Yes, with the main wiring harness connected I have no spark at all. With the starboard side 6 pin plug going into the power pack disconnected the motor starts and runs ( crappy )on the # 1,3,5 cyl. only. I also get the same results when i only unplug the bl/yw 1 pin amphenol style plug up by the powerpack.

was the key turned on and the kill switch in operational position when you checked spark with the harness plugged in? If it was, you have an issue with the key switch, kill switch or the harness itself. You could still have otehr issues with the engine side. You're going to need a dva meter to diagnose any further. If you want to try a couple other things, shin a flash light under the flywheel, look for the magnets to be out of position, cracked or stuck together. Secondly, swap the leads to the coils form one side to the other, see if the spark moves with it, if it doesn't and still fires on 1 3 5, check the coils grounding straps, they are known to corroded and not ground. Pull the cover off the power pack, look under the cover and make sure you don't have any wires pinched, pull each an-phenol plug apart and check the connections. Look around for any black yellow wires you haven't disconnected yet, if you find any more, unhook them and look for spark on all 6. If this doesn't get it, you're going to have to get a dva adapter

I just replaced kill switch and ignition switch so I know they are good, I will check out those other suggestions right after the storm passes, if my boat makes it through. Thanks

if you didn't have any spark with the engine harness hooked up, you still have a problem with the boat side of the electrical, whether its the harness,m key switch, kill switch or what ever, make sure you do all your testing on the engine with the harness disconnected, once you get fire on all 6, then go back and start diagnosing the boat side.
