Four stroke flat spot

Hello,
You're still under warranty, I would go to Evinrude.com, Australian Chapter and contact them, sometimes your dealer isn't the best mechanic, I hear it over an over that always find a good dealer & certified tech near your location. But tell the factory what your engine is doing and who has tried to fix it, but the minute you or a non certified mechanic touches your outboard they will give you a hard time to help you. For all we know it might be programing, it controls timing, injectors, fuel pump, air ratio, etc, etc.
Good luck
