The recommended maintenance schedule for Yamaha EX, EX Sport, and EX Deluxe Waverunners includes an initial inspection after the first 10 hours of use, followed by regular maintenance every 50 hours or once a year, whichever comes first. This includes checking the engine oil, spark plugs, battery, and cooling system.
If your Yamaha EX Waverunner is having starting issues, check the battery connections to ensure they are clean and tight, inspect the spark plugs for wear or fouling, and verify that there is sufficient fuel in the tank. If problems persist, consult the owner's manual or a qualified technician.
To store your Yamaha EX Waverunner for the winter, thoroughly clean and dry the unit, stabilize the fuel, change the oil and filter, disconnect the battery, and store it in a dry, cool place. Consider using a cover to protect it from dust and debris.
