2007 Evinrude 250 H.O. - Again

Do You Have the diagnostic software ? If so can you do a data log report for me of the last 5 minutes of running and i will take a look for you.
Had allready problem with pum/ reservoir and fixed it allready.

Spark plugs are new and mounted in proper direction

I think it could be problem with heat sensors. It told me 25 degree when it was freaking cold outside and the engine didn't run. But still would 3 of them broke at one time? portboard, starboard and EMM ??

Had same problem with our 250, fault lay in tacho, replaced it and problem solved - good luck.
