hi mates, I am new to this forum, I am writing on behalf of my longtime mechanic who does not do computers very well.
I have a 2002 mercury saltwater 150 outboard with low hours, which you could probably eat off of, for reals.
The most recent repair required replacing the stator. My mechanic also did a tune up decarbed the carbs and installed new plugs, but I think the stator was the major culprit of my last engine trouble. first question, can you get a partially working stator from the manufacturer.
The current motor trouble is that the motor runs smooth from idle to 2100 rpm, then when applying throttle, it develops a coughing or stuttering. This stuttering or missing occurs up to about 3700 rpms, but from there to 5100 rpms or the top end it seems to run and sound fine. The mechanic went for a ride with me to ascertain if I was correct or not in thinking we still had an issue, he agreed, something not right here.
He had it another full day without coming up with anything else. my first thought was that the stator he just installed was defective from the factory, not sure if that is possibe. He checked the ignition and coils, but apparently did not think that was an issue. Does anyone have any ideas about what could be possibly causing this missing or coughing between low and high rpms? Thanks in advance for any and all comments suggestions.
