The recommended fuel type for the Yamaha FX HO 2010 Waverunner is regular unleaded gasoline with a minimum octane rating of 86.
It is recommended to change the oil every 50 hours of operation or at the beginning of each season, whichever comes first.
Use a high-quality 4-stroke marine engine oil, such as Yamalube 4W, which is specifically formulated for Yamaha WaveRunners.
Check the battery to ensure it is charged and connected properly. Verify the fuel level and inspect the spark plugs for wear or fouling.
Connect a garden hose to the flushing port, start the engine, and then turn on the water. Run the engine for a few minutes, then turn off the water and shut down the engine.
Regularly wash the hull with fresh water and a mild detergent. Inspect for damage and apply marine wax to protect against UV rays and water damage.
Turn off the engine immediately to prevent damage. Check for debris blocking the intake grate or cooling lines, and ensure the cooling system is functioning properly.
Drain the fuel tank or add fuel stabilizer, change the oil and filter, flush the cooling system, and store the Waverunner in a dry, sheltered area.
Store it in a cool, dry place on a trailer with a cover to protect it from dust and moisture. Ensure the battery is disconnected or maintained with a trickle charger.
Regular maintenance is key. Consider upgrading the intake grate or impeller to enhance performance, but ensure any modifications comply with local regulations.
