The recommended maintenance schedule includes checking the oil level every 10 hours, changing the engine oil and filter every 50 hours or annually, inspecting and cleaning the spark plugs every 100 hours, and checking the fuel system regularly for leaks or damage.
To winterize your Yamaha VX Waverunner, start by cleaning and drying the exterior, flush the cooling system with fresh water, stabilize the fuel, change the oil, grease all fittings, remove the battery and store it in a cool, dry place, and cover the Waverunner with a breathable cover.
If your Waverunner won't start, check the battery for charge and connections, inspect the spark plugs for wear or damage, ensure the fuel tank has fresh fuel, and verify that the safety lanyard is properly attached. If issues persist, consult a Yamaha service technician.
To improve fuel efficiency, maintain a steady speed, avoid rapid acceleration, ensure the hull is clean and free of marine growth, perform regular maintenance on the engine, and use the recommended fuel grade.
Yes, you can use your Yamaha VX Deluxe in saltwater. After each use, thoroughly rinse the exterior and flush the engine with fresh water, apply a corrosion inhibitor to metal parts, and check for any signs of corrosion regularly.
Attach a garden hose to the flush port on the rear of the Waverunner, start the engine, and then turn on the water. Let it run for a few minutes, revving the engine occasionally, before turning off the water and then stopping the engine.
Check for obstructions in the cooling system, ensure the impeller is not damaged, verify the water intake is clear, and inspect the thermostat for proper operation. Regularly flushing the cooling system can help prevent overheating.
Yamaha recommends using Yamalube 4W 10W-40 oil, which is specifically formulated for their four-stroke Waverunners, providing optimal performance and protection.
Inspect the impeller by removing the pump and visually checking for nicks, bends, or other damage. The wear ring should have minimal clearance with the impeller; excessive clearance indicates wear and may require replacement.
Common signs include difficulty starting the engine, reduced performance, poor fuel economy, and engine misfires. Inspect the plugs for wear or carbon buildup and replace them as needed.
