I HAVE A JOHNSON 200HP 1989 MOTOR . THE SPARK PLUGS SEEM TO FOUL WHEN I TRY TO START THE BOAT AFTER ITS BEEN SITTING FOR A FEW DAY. HOW CAN I CORRECT THIS PROBLEM?
Start by letting us in on more about what you have. What spark plugs are you using? What grade fuel? What oil? Has it been sitting long? Carbs clean? Sync and link in adjustment? Thermostats in?
