My 18 Classic (350 Mag Alpha) after warming up runs rough at low RPM, accelerates normaly and runs perfect at speed, however when coming off of plane around 1600 RPM and below gets extremely rough. Sounds as if all eight aren't firing. Boat was previously in Colorado. Now close to sea level. Also a little more than normal soot on transom after each use.
Any ideas? Thanks,
