This past weekend I had troubles with having to hold my starter in about 10 sec before the jet ski would start. Even when I was out in the water the jet ski would turn off and it would take 10 sec or more to start my ski. Sometimes it would just kill my battery then needed to get towed in. I would then charge my battery and it would start right back up, but still would take a while. I have a primer and a new battery before this weekend. What else could it be.
