The recommended maintenance schedule includes checking and changing the engine oil every 50 hours, inspecting spark plugs every 100 hours, and flushing the cooling system after each use in saltwater. Additionally, inspect the hull and propeller for damage regularly.
First, check the battery connections and ensure they are clean and tight. Verify that the battery is fully charged. Inspect the spark plugs for wear or fouling, and replace if necessary. If the issue persists, consult the owner's manual for further diagnostic procedures.
Use a high-quality 2-stroke marine engine oil that meets NMMA TC-W3 standards. Yamaha's own brand of 2-stroke oil is recommended for optimal performance and engine protection.
Rinse the Waverunner thoroughly with fresh water after each use, especially in saltwater environments. Apply a corrosion inhibitor spray to metal parts and connections. Store the Waverunner in a dry, covered area when not in use.
To winterize, stabilize the fuel with a marine fuel stabilizer, run the engine to circulate, then fog the engine with fogging oil. Drain and flush the cooling system with antifreeze. Remove the battery and store it in a cool, dry place. Cover the Waverunner and store it indoors if possible.
Connect a garden hose to the flushing port, start the engine, then turn on the water. Let it run for a few minutes to flush out salt and debris. Turn off the water first, then shut down the engine to prevent water from backflowing into the engine.
Excessive vibration can be caused by a damaged or unbalanced impeller. Inspect the impeller for damage or debris. Additionally, check the engine mounts for wear or damage and replace any faulty parts.
Inspect the fuel lines and connections for any visible signs of wear, cracks, or fuel stains. Pay close attention to the fuel tank and fuel pump area. If a leak is suspected, it is advisable to consult a professional technician for repairs.
Immediately shut off the engine and let it cool down. Check for blockages in the cooling intake. Ensure the cooling system is flushed regularly. If the problem persists, seek professional assistance to inspect the thermostat and water pump.
First, remove the engine cover to access the spark plugs. Use a spark plug socket to remove the old plugs. Check the gap on the new plugs according to the manufacturer's specifications before installation. Tighten the new plugs by hand, then use a socket to secure them snugly.
