Recently bought a 2005 GTX Limited 215 with 220 hours. Last year I had a 2009 Speedster 150, with a 2012 255hp motor (sold due to lack of use, as I work weekends). Now I can just get out on the jet ski without needing someone for a counter-weight on the boat. Lol. Just had the supercharger rebuilt (220 hours and the previous owner had no idea if it was ever rebuilt), and ordered a new Solas prop and wear ring. :)
I had purchased "SBT carb rebuild kits", assuming any kit was as good as any other....WRONG! Ski would not throttle up on the water (ran fine on the trailer). Replaced SBT kits with Mikuni OEM kits.....blast off...ski was back to normal...better than normal actually, has never run better.
