I own a 2008 GTX 215. The reason it is heavier has a lot to do with why it is 60 more HP, the supercharger, intercooler, plumbing and hardware. I think the $1,000 is well spent considering what you are getting for it. My GTX will top out at 68 MPH.Anybody have opinions about the differences/value of the Sea-Doo GTX 155 vs. the 215? Very few technical differences that I can see. The 215 is heavier for reasons I don't know, and I've see some comments that it's more stable, but $1,000 worth of stable?
