I JUST RECENTLY BOUGHT A USED 1988 18' GLASSTREAM BOAT WITH A MERCURY 150HP BLACK MAX.I HAVE A LITTLE PROBLEM WITH A FIRING DISORDER.<br />3 OF MY CYLINDERS ARE NOT FIRING ON THE SAME SIDE OF THE BLOCK AND PLUGS ARE NEW, PLUG WIRES AND COILS ARE NEW. I JUST CAN'T SEEM TO PINPOINT THE PROBLEM. I WOULD BE MOST GRATEFUL TO HAVE YOUR ADVICE ON THIS PROBLEM

You have two switch packs on this engine. It sounds like one of them has gone bad.
