Hey, i bought this waverunner and it would only run for a hour or two then it would shut off. Then i lend it to my brother. He left it under a tree with the plugs in, so it was filled with water for a couple of months. now, we bought a new cdi and spark plugs. The engine turns over but does not start. I was wondering if you guys would know whats wrong and how or if i could fix it.
