The recommended maintenance schedule includes checking the engine oil and coolant levels before each ride, inspecting the hull and deck for damage, and cleaning the jet intake and impeller. An annual service by a certified Yamaha technician is advised to ensure optimal performance.
If the Waverunner won't start, check the battery connections and charge the battery if necessary. Inspect the fuel system for any blockages or leaks. Ensure the safety lanyard is properly attached and the engine stop switch is in the correct position.
Yamaha recommends using Yamalube 4W 10W-40 oil, which is specifically designed for marine engines, providing corrosion protection and optimal lubrication.
Attach a garden hose to the flushing connector, located at the rear of the Waverunner. Start the engine before turning on the water to prevent flooding. Allow the water to flow for a few minutes to flush out salt and debris. Turn off the water before stopping the engine.
Rinse the exterior with fresh water to remove salt and debris, using a mild soap if necessary. Dry the Waverunner with a soft towel and apply a marine-grade wax for added protection. Clean the seats and dashboard with a UV protectant to prevent fading.
To improve fuel efficiency, ensure the Waverunner is regularly maintained, including checking spark plugs and air filters. Avoid rapid acceleration and maintain a steady throttle during rides. Keeping the hull clean and free from marine growth will also help.
Check for debris blocking the jet intake and impeller. Ensure the cooling system is not clogged and is functioning properly. Inspect the coolant level and top up if necessary. If the problem persists, consult a Yamaha technician.
Clean and dry the Waverunner thoroughly. Add a fuel stabilizer and run the engine for a few minutes to circulate the treated fuel. Remove the battery and store it in a cool, dry place. Cover the Waverunner with a breathable cover to protect it from dust and moisture.
Vibration issues are often caused by debris in the impeller or damage to the impeller or driveshaft. Inspect and clean the jet intake and impeller. If the impeller or driveshaft is damaged, it may need to be repaired or replaced by a professional.
The FX Cruiser HO is equipped with features such as the Yamaha Security System with remote transmitter, dual mirrors for improved visibility, and a reboarding step for easy water access. Always wear a life jacket and use the safety lanyard for added protection.
