I took my 95' XP out last weekend and the jetski wouldn't start. I tried to start it on the trailer first and it seemed like it was going to, but after a couple of time with no success, it just started to click and the battery light is on. The battery is 3 months old and all of the connections to the battery are clean and tight. I was just wondering if I could get some insight as if it could be the battery or possibly the starter? It is a West Marine sealed AGM battery that is 18 amps. It seems like it wants to go but it starts to turn over very slow and then after a couple of seconds then it just clicks. Should I try a new battery first, and if so, should I go with a 19 amp instead? Also, the week before that when there was no issue with the battery, the ski seems to rev up fine, but it doesn't seem to go anywhere, it just has a pinging kind of sound to it when I give it gas, it revs but no acceleration. It sounds like seaweed was stuck in it, but everything was clear. Could it be that there is no oil in the jet pump cause I haven't checked that recently. If so, where is the jet pump located so I can check the oil? Any help would be appreciated, Thanks!!
