How to Fog a Johnson Outboard
Fogging a Johnson outboard needs to be done each year when the motor is being winterized and the end of the season and is no longer being used. Fogging will coat the inside of the carburetor and the cylinders in the motor with an anti-corrosive oil. You can fog your Johnson outboard by first taking the boat out of the water at the end of the boating season.
