NGK Spark Plugs For Inboard Outboards

NGK spark plugs for inboard outboards are made specifically for marine applications. They are used to produce a spark to ignite an air-fuel mixture, making it possible for a boat to start easily and run efficiently. These plugs are especially effective for off-shore adventures. They provide excellent reliability and performance, making them an excellent replacement for everyday engine maintenance.

Most marine engines come with a label that specifies which spark plugs are compatible with the engine. The spark plugs should be changed according to the manufacturer's specifications. If the spark plug is not working properly, it can be a major hindrance to the performance of the engine. In addition, spark plugs can become damaged over time, so they need to be replaced regularly. Fortunately, this is not a difficult job.

To check for proper spark plugs, you will need to first check the spark plug's insulator tip for cracks and damage. If you see chips or holes in the insulator tip, you will need to replace it. The insulator tip can also become damaged from excessively tightening the seat plugs. The seat plugs should be finger tight. They are typically backed up with a rubber shell that grips the insulator. If the seat plug is not finger tight, you should tighten it by about a quarter turn.

If the spark plug has a smudge of black soot on the electrodes, it is carbon-fouled. This can happen when the engine is running too rich, or when the engine has not been cleaned for a long time. It can also happen when the engine has been left idling for a long time. The insulator tip can also become oily, which can cause the plug to leak oil from the tip.

In addition, a faulty ignition lead, a sticking valve, or a clogged flame arrestor can cause cold fouling. These deposits can short-circuit the ignition pulse, making it harder for the engine to fire properly.

Another common problem with spark plugs is a chipped insulator. This occurs when the plug is overheated or over-gapped. If you have a chipped insulator, you will need to replace the plug. The insulator can also become chipped if the plug is re-gapped. Using a spark plug gapping tool can help you determine the gap for the plug. You can also purchase dielectric grease to apply to the ends of the plug. This will help reduce the amount of insulator chips that can occur.

Some boaters prefer to change their spark plugs on a regular basis. If you are unsure of how to do this, you can consult a professional mechanic to assist you. In addition, your owner's manual can provide a guide for identifying which spark plugs are suitable for your engine. If you do not have a spark plug wrench, you can use a gap gauge. However, be sure to use the recommended plugs.

NGK's marine spark plugs are designed to ensure excellent reliability and performance. These plugs provide the solution for off-shore adventures. Whether you are running a two-stroke outboard or a four-stroke jet boat, NGK has the plug for you.
