The Right Plug






With today's modern fuel injection engines, changing your spark plugs is few and far between. there still is a possibility that the day will come that you will need to know how to properly change a spark plug on your boat. That is where we come in. Here are some tips and tricks for changing your spark plugs.

The Right Plug

A tad short or not the right heat range won't fly. Close enough will not work when installing spark plugs. The best way to figure out the right spark plug is to contact the manufacturer. 

The Right Wrench

Spark plugs have a porcelain tip on them that is protected by a foam cover. Using a standard socket wrench could crack the porcelain. You will need a steady hand, socket extension and tight griping socket.

The Right Torque

Over tightening is one of the biggest mistakes. If you overtighten the spark plug when reinstalling it, your could strip the cylinder which would be costly to remove and have it re-threaded. The average torque wrench setting should be between 18-20 pounds per square inch. Make sure to check with the manufacturer before use.

The Right Gap

The gap is the distance the spark has to jump. If you have a gapless engine, then this is one step that you do not have to worry with. If your sparks need to be gapped, I would suggest investing in feeler gages. The gap setting can be found on the emissions plate of the engine or in the owner’s manual

Quick Tip: As you are changing your plug, check the others. Look for water droplets, aluminum bits, or a white substance on them. If you find any, take it to your dealer before you head out again.

Now that you know how to change your spark plugs, don't let the fear of what might go wrong stop you from enjoy a day relaxing on the water. If you are looking for some more tips on the subject, check these out
