The recommended maintenance schedule includes checking the engine oil, spark plugs, and fuel lines every 10 hours of use or monthly, whichever comes first. Additionally, it's important to inspect the hull and clean the cooling system regularly. An annual professional service is also advised.
If the Waverunner won't start, check the battery connections for corrosion and ensure the battery is charged. Inspect the spark plugs and replace them if necessary. Also, verify that the fuel is fresh and that the fuel lines are not clogged.
Yamaha recommends using Yamalube 2-W Oil, which is specifically designed for wave runner engines, providing optimal performance and protection.
To improve fuel efficiency, ensure that the engine is well-maintained, with clean air filters and properly gapped spark plugs. Avoid carrying unnecessary weight and maintain a steady speed while operating the Waverunner.
Common causes of overheating include clogged cooling water passages, a faulty thermostat, or debris in the water intake. Regular inspection and cleaning of these components can prevent overheating issues.
For off-season storage, clean the Waverunner thoroughly and ensure it's dry. Add a fuel stabilizer to the tank, and remove the battery to store it in a cool, dry place. Cover the Waverunner with a breathable cover and store it in a sheltered area.
Before using in saltwater, apply a corrosion protectant to metal parts, and after each use, rinse the Waverunner with fresh water, including the cooling system, to remove salt residues. Regularly check for any signs of corrosion.
Use a mild detergent mixed with water and a soft brush or sponge to clean the hull. Rinse thoroughly with fresh water and dry with a soft cloth. Avoid harsh chemicals that can damage the gel coat.
If you notice water ingress, check the drain plugs to ensure they are securely fastened. Inspect the hull for any cracks or damage. If the problem persists, consult a professional technician.
To change the spark plugs, first remove the engine cover. Then, disconnect the spark plug wires and use a spark plug socket to remove the old plugs. Install the new plugs, ensuring they are properly gapped, and reconnect the wires.
