Carl, Thanks for your reply. I will try to write a detailed response later, but I just thought I should mention that it is a 2006 Kawasaki STX-15F, with a four-stroke engine: http://www.jetski.com/article.cfm?id=615 Needless to say, I too feel that $2500 for the damage (even if it was our fault) is excessive.
