The Kawasaki 750 ZXI Jet Ski is a two-seat watercraft that is designed for regular use. If problems are encountered when using the Kawasaki 750 ZXI, the user should perform basic troubleshooting steps. Following these steps can often identify the cause of the problems. Once the cause of an issue with the Jet Ski has been correctly identified, a remedy for the problem can be put into place in many cases.

Skill level:
Moderately Easy



  1. 1

    Fill the fuel tank if the engine turns over but does not start. An empty or low fuel tank will prevent the engine from starting.

  2. 2

    Check the battery connections if the engine will not turn over when you attempt to start the ignition. Tighten the connections if they are loose.

  3. 3

    Replace the battery if the battery connections are secure and the engine will not turn over. Low battery voltage will prevent the engine from starting.

  4. 4

    Replace the spark plugs if the engine misfires. Worn out spark plugs can cause an engine to run rough or misfire.

  5. 5

    Turn the engine off and check the jet pump for debris or weeds if the engine overheats. Debris in the jet pump causes the engine to have to work harder.

  6. 6

    Contact a Jet Ski service technician if the steering is erratic. A damaged steering cable can cause erratic steering. Faulty steering is dangerous so a technician should inspect it.
