I accidentally put Mercury 300x in breakin mode...how do I get it out?

Is there any way to get it out of breakin mode other than running the 2 hours?

I don,t think thats possible ,maybe someone that can alter the ECU like Matt Riddle ,or Sean Hill Rapair,
you can drive the engine ,no problemo ,its going to run a little richer on fuel and oil ,and limited rpm,s cause the ECU thinks it has to run rich to break in a new powerhead .
Did you do this with the ignition on and the shift lever ?

Yes i did. Didn't know thats how you did it till we connected it to computer. I only have about 30 mins left on break in but just annoying to have to use 30 more mins on breakin.
