The recommended maintenance schedule includes regular checks every 10 hours or monthly, whichever comes first. This includes inspecting the engine, checking the jet pump, and testing the battery. Annual maintenance should include oil changes, spark plug replacement, and a thorough inspection of all systems.
To winterize your Waverunner, flush the cooling system with fresh water, add a fuel stabilizer, change the engine oil, lubricate all moving parts, remove the battery and store it in a cool, dry place, and cover the Waverunner to protect it from the elements.
The 2013 Yamaha FZS Waverunner requires Yamalube 4W 10W-40 oil, which is specifically formulated for Yamaha marine engines. Always refer to the owner's manual for confirmation.
If the Waverunner won't start, check the battery connections, ensure the battery is fully charged, inspect the spark plugs, and make sure there is enough fuel. If the problem persists, consult a professional technician.
If your Waverunner is overheating, check for blockages in the cooling system, ensure the coolant level is adequate, and inspect the impeller for damage. Running the engine out of water can also cause overheating, so ensure it's submerged when operating.
To check and fill the coolant, locate the coolant reservoir, remove the cap, and check the coolant level. If necessary, add a 50/50 mix of antifreeze and distilled water up to the designated level. Avoid overfilling.
Common signs of a failing jet pump include unusual vibrations, loss of power, cavitation, and excessive noise. Regularly inspect the impeller and wear ring for damage or debris.
To improve fuel efficiency, maintain a steady throttle, avoid rapid acceleration, keep the hull clean, ensure the engine is well-tuned, and regularly check the alignment and condition of the jet pump.
If the Waverunner is taking on water, check the hull for cracks or damage, ensure the drain plugs are secure, inspect the seals around the pump and the engine compartment, and check the bilge pump for proper operation.
To replace the spark plugs, remove the engine cover, disconnect the ignition coils, and use a spark plug wrench to remove the old plugs. Install new plugs, ensuring they are the correct type and properly gapped, then reattach the ignition coils and engine cover.
