"I have a 1999 200 Johnson Oce
"I have a 1999 200 Johnson Ocean Runner. The motor starts great and idles fine. Once in gear it run s ok but when I run between 1200-3600 RPMs its shakes and misses like crazy. Once it over 3800 rpms the motor runs great. New plugs, Oil tank, oil line, oil pump.
Any suggestions? Thanks"
