yes it should go across the water,just get it clutched right first,you'll need lots of track speed right off the bat.a guy the works at my dealer took second place in the stock class with a ZL440,if this little sled can do it your should be able to being a 500,its all in the clutching;for starters anyway then its all you!!! hope you have fun and enjoy!!!!!
p.s. you could probably gear it down alot since your not going to be going 80mph,this would help alot!
