WARNING
When removing or installing a spark plug, be careful not to damage the insulator. A damaged
insulator could allow external sparks, which could lead to explosion or fire.
The spark plug is an important engine component and is easy to inspect. The condition of the
spark plug can indicate something about the condition of the engine. For example, if the center
electrode porcelain is very white, this could indicate an intake air leak or carburetion problem in
that cylinder. Do not attempt to diagnose any problems yourself. Instead, take the outboard motor
to a HIDEA dealer. You should periodically remove and inspect the spark plug because heat and
deposits will cause the spark plug to slowly break down and erode. If electrode erosion becomes
excessive, or if carbon and other deposits are excessive, you should replace the spark plug with
another of the correct type.
