Hello to all. I have a 1997 Mercruiser 5.7lx bravo III out drive. Looking for some direction and help (a course! right). On the water yesterday (Sunday9) cruising around 31K rpms for about 45min, no problems. After slowing down to a stop, do to a several floating logs, then getting underway again, I had a misfire at 2k rpms, I never experience that with this engine before. I slowed down again and it happen again, same thing at the 2k rpm. The engine runs fine under and above that 2 mark, however misfired every time at 2k rpm. Any ideas? Thanks in advance.
