Re: E-TEC G2 300 hp Hesitation in 1800-2200 RPM Range

Because the transition rpm zone is based on engine load, see if you can borrow the next size larger prop and see if that minimizes the roughness. Also check with your dealer to see if there are any software updates to your engine.

Re: E-TEC G2 300 hp Hesitation in 1800-2200 RPM Range

I too have the 300 G2 (2017) exhibiting the same issues. Although my problematic range is 1300-2200. The dealer explained similarily to what everyone here is saying, however, I'm having a hard time wrapping my head around the "nothing can be done" answer. Is this truly the case?

 

FYI, I've also had 2 "code 5" excessive vibration alarms come up at WOT with no external reason. Could this be telling of a different underlying issue within the engine?

The 1300-2200 rpm range is the transition spectrum that designates when the engine is switching from the low rpm "lean" mode  to the power-developing mode. It is controlled by the EMM and is based on the engine load and rpm.

Often by changing a propeller one pitch size up or down can make a difference.
