low/mid RPM dead spot or poor combustion / rough running RPM zone

Hello E-Nation,

 

new member here with 6 hours of runs time on a band new G2 225.  All in all first impression was great, however I was surprised to find what I would describe as a rough running engine or poor combustion type thing in the 1500 to 2500 RPM range.  It seems the motor just does not want to run in that RPM range.  Admitedly that RPM range does not allow the boat to get on plane, so it is just plowing through the water and I assume exerting a heavier load on the engine.  That whole range in the throttle movement is again almost like a dead spot where nothing happens except the motor runs rough.  Once you push the throtle up farther the engine takes off and goes that a bat out of hell with no hesitating or problems.

 

The engine runs perfectly at low RPM (up to 1200) and over 2600 RPM is again smooth all the way to 5500.

 

Anyway just wondering if anyone else had the same experience. 

 

I am also wondering if I got an "H.O" motor cause I did not order one.  There is red lettering showing "HO" under the 225 on the back of the engine, but no indications on the side panels.  Motor model # is E225XHABA.  Perhaps if it is a high output engine that would explain the poor lower end running? 

 

Thanks in advance,

Steve

The letter "H" in your model designator proves that your motor is the high output HO engine. It is tuned for maximum performance.

Re: low/mid RPM dead spot or poor combustion / rough running RPM zone

thank you for that info on the high output aspect. I am not sure how this happened or how happy I am about it.

I will get some more time in the boat and see if the engine gets better or worse.

thanks, Steve
