Johnson Outboard Ignition Systems
Thirty years ago when an engine refused to start, a cranky ignition was likely the cause. Today with electronic ignition systems, it is fairly easy to troubleshoot a startup problem and should the spark plugs prove to be the culprit, a quick fix. If your engine is missing, mis-firing, or just will not start, follow these steps to troubleshoot. This way you’ll know if the issue is minor or requires more investigation by a skilled marine technician.
Here is an engine overview. For Johnson outboard ignition systems to run, the requirements are compression, fuel and spark. Sound motor function is determined by compression, the air/gas/pressure induced explosion that occurs in the pistons must be sufficient to turn the propeller. For this to work the fuel lines must not be clogged and the fuel injectors or carburetors are fully-functional. Spark from the spark plugs provides the catalyst that produces engine power.
How to Troubleshoot Johnson Ignition Systems
To troubleshoot the ignition system, start with the spark plugs. Use a spark plug socket, ratchet and extension to test the plugs. To begin, remove just one plug. Inspect the plug tip and notice if it is soaked with oil or fuel. If wet, this indicates a fuel line issue. If dry, note the color and condition of the plug tip. Tips that are blistered or melted mean the wrong plug has been used. Check your owner’s manual to determine the right plug for your Johnson outboard ignition system, simply give us a call, and we’ll be glad to assist.
