I'm new to this forum as this is my first post. I was hopeing that some of you guys would be able to help me out with a problem. I don't really know a who lot about pwc's but I do have a good bit of mechanical knowledge from working on atv's and trucks and stuff all my life. My question is this. My girl friend has got a 2001 Yamaha waverunner. It is an 800 I believe. The problem with it is that it gradually takes on water when riding it. when you first put it in the water you can ride it for probably about an hour and then you really start noticing it and then you have to take the thing out of the water and drain it. I can't find any cracks in the hull or anything like that. Anyone know what might be causing this problem? Thanks in advance. And like I said i'm new at this so don't be too hard on me.
