The recommended oil type for the 2007 Yamaha FX Cruiser Waverunner is Yamalube 4W 10W-40 or any other 10W-40 engine oil with API ratings of SE, SF, SG, SH, SJ, SL, or SM.
It is recommended to change the oil in your 2007 Yamaha FX Cruiser Waverunner every 50 hours of operation or once per season, whichever comes first.
If your Yamaha FX Cruiser Waverunner won't start, check the battery connections, ensure the fuel level is adequate, and verify that the kill switch is in the correct position. If these steps don't solve the issue, consult a professional mechanic.
To winterize your 2007 Yamaha FX Cruiser Waverunner, clean and flush the engine, stabilize the fuel, remove the battery and store it in a warm place, and cover the Waverunner with a protective cover.
To flush the cooling system, attach a hose to the flush port, start the engine, turn on the water, and let it run for about 5 minutes. Turn off the water first, then stop the engine.
Check for blockages in the cooling intake grate, ensure the cooling system is flushed properly, and inspect the impeller for damage. If the problem persists, consult a professional technician.
Regular maintenance checks should include inspecting the hull and deck for damage, checking the oil and coolant levels, inspecting the jet pump, and ensuring the throttle and steering systems are functioning properly.
To improve fuel efficiency, keep the engine well-maintained, use the recommended oil, avoid excessive idling, and maintain a steady speed while riding.
Excessive vibration may be caused by debris in the impeller or damage to the impeller or drive shaft. Inspect these components and clean or repair them as necessary.
To check the battery condition, use a multimeter to measure the voltage. A fully charged battery should read around 12.6 volts. If the voltage is lower, consider charging or replacing the battery.
