I know several of you guys run one on your Phoenix. Just wanting some reviews of the motors performance, durability and gas milage. How well does Yamaha stand behind their motors? Does anyone know the approx cost difference between the 250 Pro XS and the SHO? I have always been a Merc guy but the SHO motors look very impressive. The videos I have seen show awsome holeshot and great midrange. What is your experience?
