The recommended maintenance schedule includes an initial service at 10 hours, followed by regular maintenance every 50 hours or annually. Key tasks include oil changes, checking the cooling system, and inspecting the impeller and pump.
First, check the battery to ensure it is fully charged and the terminals are clean. Examine the fuses and ignition switch for any faults. If the problem persists, consult a professional technician.
For optimal performance, Yamaha recommends using Yamalube 4W 10W-40 oil or a similar high-quality 4-stroke marine-grade engine oil.
Drain any water from the cooling system, add a fuel stabilizer, fog the engine, remove the battery, and store it in a warm place. Cover the Waverunner to protect it from the elements.
Check the cooling intake for blockages and ensure the water pump is functioning properly. If the issue persists, verify the thermostat's operation and consult a professional if needed.
Maintain a steady speed, avoid sudden accelerations, and ensure regular maintenance. Properly inflated tires and a clean hull can also contribute to better fuel efficiency.
Excessive vibration can be caused by a damaged impeller or debris in the pump. Inspect these areas and clear any blockages. If damage is found, consider replacement or repair.
It's recommended to inspect the spark plugs every 50 hours of operation and replace them as necessary, typically every 100 hours or once per season.
Attach a garden hose to the flushing connector, start the engine, and then turn on the water. Allow the engine to idle for several minutes before turning off the water and then the engine.
Regularly wash down your Waverunner with fresh water after use, especially in saltwater. Apply anti-corrosion spray to metal parts and consider using a protective wax on the hull.
