Boat does not have one. Have also bypassed harness with key box. And nothing

Update. Boat is fixed. After all ignition checked out it ended up being the red wire on the middle ecm connector had o volts but up top it had 13 volts the wire broke inside the jacket at 1 inch out of connector in a bend. No corrosion no melted wire nothing. Repaired wire and started instantly. Factory defect. Yamaha part of my mercury wire harness
