Could this be an EMM or senser problem?

2009 ETEC-250 HO,  200hrs.  No previous problem but last week engine suddenly bogged down when I tried to accelerate as if it was only  going on half it's cylinders  Took it in to Evinrude dealer and had plugs replaced, new fuel filter and I assume they checked for error codes. They said everything worked during trial run,  I took it out and at first worked normally but then second time I started it up it  bogged down again when I tried to accelerate. Now I am wondering if it was just going into S.A.F.E.mode  for some reason. No warning lights or beeps came on.. Could it be a bad senser problem or bad EMM?  I will be taking it back to the dealer after the holidays but woulld like any suggestions I could offer the dealer to check..  They said everything worked fine after

Ask your dealer technician to ride with you and have his test equipment onboard so he can troubleshoot when the motor acts up.

 

If the motor is going into SAFE mode, it will be limited to 1200 rpm and will run rough if you try to exceed that rpm but will run normally below 1200.

Took boat to dealer and they just called and said they are getting error code for the #4 fuel injector. He said they cleared the codes and repeated test and same error code for the #4 fuel injector came up. I guess I will have to replace the fuel injector which is quite expensive considering I only have 200 hrs on the engine. Does this bad fuel injector sound like it is the cause for my engine bogging down when I try to accelerate?

Yes, a faulty injector would affect acceleration and full power output.
