I hooked up the garden hose to the flush connection on my ski's yesterday. I started the ski, turned the water on full blast and there was water spraying in one spot from each of the sea doo's head gasket/upper O-ring area. On one of the ski's the o-ring had actually bulged out a bit. The water was a very small but high pressure spray/stream of water. It reminded me of a water hose under pressure with a very tiny hole in it where a very fine but high pressure spray of water comes out. So, I'm guessing I need to replace the head gasket/O-ring. The sea doo parts diagram shows it as an O-ring with part # 420950360. The ski ran flawlessly and I took pictures of the block and the area right around the leak this morning to make sure there were no cracks in the block. I'll take a few more tonight and then post. So, a few questions:

1. Is this a common problem at all?
2. Is the O-ring difficult to replace?
3. Did I do this myself by turning the water on full blast?

Thanks in advance. I look forward to your replies......I think!

OH CRAP! The pictures don't lie. It looks like it's the cynlinder gaskets, not the head gasket. Is that right? Ok, go ahead, lay it on me...How bad is it?
