2018 chaparral vortex 203...engines will not start

[Khudman]

hello, we just bought a new 2018 Chaparral vortex 203 with the duel engines. We took it out on the water today a ran it for a little while and then stopped to let our kids swim. When we got back in the boat the engines would not crank. It will turn over but will not start. Does anyone know what might be the problem?

Only thing that quickly comes to mind is that the throttle was in neutral and the kill switch want pulled

We tested both and that was not the problem

Have you found your problem, was fault U0300 displayed in the gauge?
That would be a security exchange between gage & ECMs.
If that's the case you can always start the boat by disconnecting the gauge & re-setting the ignition key.
