To flush the engine, attach a hose to the flushing port, start the engine, turn on the water, and let it run for about 5 minutes. Ensure the engine is off before disconnecting the hose.
Use Yamalube 4W 10W-40 oil, which is specifically designed for Yamaha WaveRunners to ensure optimal performance and protection.
Check the battery connections for corrosion, ensure the kill switch is in place, and verify there's enough fuel. If the issue persists, consult a professional technician.
Perform basic maintenance every 50 hours or annually, including oil changes, spark plug checks, and inspecting the hull and impeller. Refer to the owner's manual for detailed schedules.
To winterize, drain the fuel system, add a fuel stabilizer, run antifreeze through the cooling system, remove the battery, and store it in a cool, dry place.
Check for debris blocking the cooling intake, ensure the cooling system is functioning, and verify the coolant levels. If overheating persists, consult a dealer.
Maintain proper engine tuning, keep the hull clean from algae and debris, ensure correct tire pressure on the trailer, and operate at optimal speeds.
Inspect the impeller and wear ring for damage or debris, check engine mounts, and ensure the drive shaft is properly aligned.
Access the engine compartment, remove the ignition coils, unscrew the old spark plugs, and install new ones with the correct gap settings. Tighten them securely and reattach the coils.
Look for reduced acceleration, unusual noises, and visible nicks or dents on the impeller blades. Regular inspection is advised to maintain performance.
