I have owned 2 Skeeters. The first was a 1994 zx150 with a 150 Merc and it was a great boat. The second which I still have is a zx250 with a 250 Yamaha. It is an excellent boat. It runs great and has a good hull shot. There are very few boats that I would consider other than a Skeeter. I don't know much about the about the sx but it should be a great boat. If you would like give me a call at 502-664-5921 I would be glade to answer any questions you may have. Also check out bassboatcentral.com Ryan.
