Boat will not start, any ideas?

Good Evening everyone.

2003 seapro / 2003 Yamaha F115txrb

No start with Key. I can jump the solenoid and it fires up. So I replaced the solenoid, still not working. When I turn the key I hear a sound like the fuel pump priming.

Thanks,
Mike

Probably the fuse. Check for 12V at the red wire at ignition switch.

Checked all the fuses & checked for 12v at the switch all are good. I have found that I don't have power at the brown trigger wire going to the starter relay, while I'm trying to start it.

Never heard of the trigger going to the starter solenoid. The trigger goes to the control box. The rectifier / regulator does go to the starter solenoid. Brown wire is Start circuit Low speed charge coil; Positive "+" potential to oil transfer pump; SW2 transfer on position V4 according to the color code chart. I can't find a wiring diagram.

When I say trigger wire I'm talking about the little brown wire in the starter relay pic.

I found out this morning that the ignition switch is bad.

FYI: If everything checks out you can bypass the ignition switch by connecting the red wire from the switch and brown wire from the neutral only start switch. So until my new ignition switch comes in, I have placed a push button between the red and brown wires, so I start the motor. Thanks for all the help everyone.
