I have a 2011 promo ProStar 197 WTT with a 5.7 Ilmor that is in awesome condition. I have maintained it meticulously and the boat has been used only for 3 event skiing/training on fresh water. It is dialed in and skis awesome. Most of the hours are due to tricks. The water pump was replaced at about 300 hrs and the fuel pump finally went out at 1300 hours. I didn't intend to sell this boat but because MC has changed hulls I decided to buy a Malibu for the next season and sell this boat. The boat now has 1450 hours. Prospective buyers inquire about the boat because the price is good; 29,900 but once they hear the hours I don't hear from them again. I would be interested to see what your experience is with high hour boats and what can realistically be expected before the engine needs to be replaced. The engine purrs like a kitten and there are no oil leaks or other issues to speak of.
