No spark

I have twin 97 Johnson 150 after using one day had problem with proper shifting on one. At home I put water to it and was satisfied with adjustments and a couple minutes later it stalled out. It turns over strong but no spark. Swapped ignition switch's to take out safety stop as possible culprit but the other still starts but starboard still doesn't. No fuse blown but swapped with port engine anyway. Now I have swapped out relays, voltage regulator, power pack, all plugs, optic sensor, stator and starter with the hope that I would clean or come across a connector or anything that was suspect. Disconnected shift linkage to be sure it was truly in neutral and have cleaned and dielectric greased everything. 110psi on every cylinder so no excuse to re-power. I question if something is grounding but not obvious. Any thoughts on possibilities would be appreciated. Thanks

Thanks. That was a bit of reading. I'm thinking only things I haven't tried but I will as soon as it's not raining (sw florida summer) is disconnect the plug with bl/y, bl/o, bl see what happens then try disconnect yellows from stator and see what happens but have no idea where to find a mercury tilt switch to disconnect to see what happens. Any chance anyone knows if my engine has one and if so where it's located or not a chance being the no spark problem?

Trouble shoot guide said it was a 4-way plug to disconnect that was going to be bl/y, bl/o, bl and doesn't matter because there are no 4-way plugs on my engine. But I did disconnect the yellows from stator and try then I individually disconnected every other plug one at a time and try to start but no spark. More wasted efforts. Any body have any idea short of deep6. Obviously I'll try most anything. Thanks
