Hello all

I have noticed that oil comes bubbling up from my Johnson outboard motor. I don't know anything about boat motors and wondered if someone could point me in a direction to troubleshoot.

First pull one plug wire off at a time with an insulated pliers and see if you have a dead cyl when it is running. If you find one it could be spark, compression or carb.
