Oftentimes people have problems with their Personal Water Craft not running properly. There are of course many reasons for this. It will require an effective inspection.

First off I recommend a Service Manual and the Owner's Manual for the make, model and year of production of the Personal Water Craft you are working on.

I would suggest a simple inspection for you.

Get out your recommended tools for spark plug inspection tools, put on your safety glasses and gloves and start a simple diagnostic.

Most of the time the issues are battery, spark plug or contaminated fuel problems.

If you need to inspect your spark plugs, the wire boots have to be removed first. Be careful when removing.
Use a pair of spark plug pliers.

Look closely at your spark plug rubber covers (wire boots). I wrap mine in a rag and use carefully.

Look for any cracks, creases or separation.

Damage can happen by the person working on it when the boots are removed.

Why is that? Some of the cylinder heads have the plugs recessed, such as a Kawasaki Ultra model.

There can be good contact between the rubber and the metal making it difficult to remove the boot.

Sometimes people pull too hard or a use a sharp metal tool that can damage the rubber.

In our training courses our students are learning. Sometimes they do not quite understand yet and the pressure they exert they can accidentally break the rubber or pull the plug cap off.

Here is a photo of one on the header. They are easy to replace.

Remember when replacing to use dielectric grease. It does take time to get to know your model.


Faithfully yours,
