I have a 2008 Searay 250SLX with a mercruiser 350 MAG. Since the middle of last summer I have been getting a System Fault (Engine Misfire) (STBD System Fault 71). I have taken it to the only local Mercury shop and they have been unable to resolve the issue. When they connect their computer, the data does not provide and specific information. They have changed it distributor cap, plugs, etc, but no resolution. Has anyone run across this scenario before?
