OK all, brand new to the forum as I have not had any problems. Since that issue has been remedied, I am now here.

The issue: The Port motor will not even sound the pre-start beep. I switched the harness on the key switch, Switch is good. Starboard motor starts right up. The starboard engine runs great at all times (Except now that I said that out loud, I am most likely screwed.) The main cables are clean and in great condition. The fuses are good. I am not sure where the neutral safety switch is, so I can't check that. The safety lanyard is fine. The rear pumps clean out hatch switches are good.

Anyone know the next step?

Besides turning it into a reef?

Just curious how you determined the rear hatch switches are good. That is one of the few issues that will stop all starting activity.

If you're sure the hatch switches are good it could be the main fuse on the ECU box (not sure where that's located on the newer boats). Could also be a starter solenoid.

I agree with @Gym. Make sure you swap plugs (like you did with the ignition) to eliminate the lanyard, clean out and neutral switches. I’m not exactly sure how the neutral switches work, but they should be below the throttle controls.
