The recommended maintenance schedule includes a pre-ride inspection, freshwater flushing after each use, oil changes every 50 hours or annually, and a thorough inspection of the hull, engine, and electrical components every year.
First, check the battery for charge and connections. Ensure the lanyard is properly attached. Inspect the fuel level and fuel lines for blockages. If these steps don’t work, consult the service manual or a professional technician.
Yamaha recommends using Yamalube 4W 10W-40 oil, which is specifically formulated for WaveRunners to ensure optimal performance and protection.
Attach a garden hose to the flush port, start the engine, and then turn on the water. Allow the water to run through the system for about 5-10 minutes. Turn off the water before stopping the engine.
Check for debris blocking the intake grates or cooling water lines. Ensure the cooling system is not clogged. If the issue persists, inspect the thermostat and water pump, and consult a professional if necessary.
Maintain a steady speed, avoid rapid acceleration, keep the hull clean from marine growth, and ensure regular engine maintenance to improve fuel efficiency.
Clean the WaveRunner thoroughly, drain all water from the engine, add fuel stabilizer, remove the battery and store it in a cool, dry place, and cover the WaveRunner to protect it from dust and moisture.
Locate the spark plugs on the engine, remove the spark plug cap, use a spark plug wrench to unscrew and check the plugs for wear or deposits. Replace with new plugs if necessary, ensuring they are properly gapped.
Common symptoms include vibration, reduced acceleration, unusual noises, and decreased top speed. Inspect the impeller for damage or wear if these symptoms occur.
Rinse the WaveRunner with fresh water after each use, apply a protective anti-corrosion spray to metal components, and store the WaveRunner in a dry environment. Regular maintenance checks can also help prevent corrosion.
