im getting my waverunner ready to go for the summer and i have read somewhere that you need to use distilled water for the battery if the water is low in it. is that true or can i use tap water? it said something about the battery not lasting as long and i know you cant always believe whats on the internet. trying to get it started i have left a 2amp plugged up all week and it wouldnt start so today i will check the water level. maybe thats it. but help if you have any other ideas.
