The recommended maintenance schedule includes an initial check after the first 10 hours of operation, followed by regular checks every 50 hours or annually, whichever comes first. Key maintenance tasks include checking the engine oil, inspecting the jet pump, and checking the hull and deck for damage.
To winterize your Waverunner, first clean and dry the exterior. Then, stabilize the fuel with a fuel stabilizer and run the engine to circulate it. Drain any remaining water from the engine and add antifreeze if necessary. Finally, store the Waverunner in a dry place and cover it with a breathable cover.
If the Waverunner won't start, check the battery connections and charge if necessary. Ensure the fuel tank has fuel and that the fuel line is not clogged. Inspect the spark plugs and replace them if they are worn or damaged. If the issue persists, consult a professional technician.
To flush the engine, connect a garden hose to the flush port, start the engine, and then turn on the water. Let the engine run for about 5 minutes to flush out salt and debris. Turn off the water first, then the engine to avoid water entering the engine cylinders.
The recommended oil for the Yamaha FZS Waverunner 2015 is Yamalube 4W 10W-40. This oil is specially formulated for marine engines, providing optimal performance and protection.
To improve fuel efficiency, ensure the Waverunner is well-maintained with regular servicing. Avoid carrying unnecessary weight and ensure the hull is clean and free of marine growth. Also, operate at moderate speeds and avoid rapid acceleration.
Common causes of overheating include clogged cooling water intakes and a malfunctioning thermostat. To prevent overheating, regularly inspect and clean the cooling system and ensure the thermostat is functioning properly.
To replace the spark plugs, remove the engine cover to access the plugs. Use a spark plug socket to remove the old plugs and install new ones. Ensure they are tightened to the recommended torque and reconnect the ignition coils.
Refer to the owner's manual to identify the error code. It will provide guidance on troubleshooting the specific issue. If unable to resolve the error, consult a certified Yamaha technician for further assistance.
Regularly wash the exterior with fresh water and a mild detergent to remove salt and debris. Apply a marine-grade wax to protect the surface and store the Waverunner under a protective cover when not in use.
