Have old Johnson 5 HP outboard motor was told to use Champion plug J6C---but I later found an old sticker on the motor that listed these plugs,
Champion---J4J
AC---------M42K
Autolite----A21X
Is the Champion J6C a replacement for these older plugs????? and why does it take 2 plugs...
I can not find the model or serial number listed anywhere with Johnson and I need to know the year of the motor, the spark plug number, and the gas to oil ratio, and the type of the oil----I am very new to the boating area and need all the help I can get----thank's to all who can help
The motor...
