Hi guys, so I bought a 2001 WaveRunner xl 700 today. The guy I bought it from said it ran great until a few months ago. He said they rode it one day, went back the next day to pull it out of the water, and It wouldn't start. It seems to turn over fine, but I measured compression in both cylinders and both are next to 0. I haven't messed with major engine issues before. Should I call a mechanic and have him mess with it, should I try to rebuild myself, get a new engine? I got myself into a bit of a mess haha. Any help would be great, thanks!
