A WaveRunner can provide endless summer thrills. Properly maintaining a WaveRunner isn’t too difficult, particularly when it comes to replacing dirty oil. All you need is the owner’s manual, an oil extractor, a rag, an oil filter, and replacement oil.
Start by extracting the oil (typically 2.4 quarts) from the engine. Consult your owner’s manual to find and remove the oil filter using your rag. Next, apply oil around the outside ring of the new filter and put the filter in place. Add replacement WaveRunner oil, turn the engine on and let it run for a few minutes, then check use the dipstick to check the oil levels.
