I am buying a Barefoot Nautique with a 454 engine in it. I am wondering if anyone is familiar with this boat....they also made a "non-barefoot" model the same year witha 350 engine in it...but as I look around the web...the models with the 350 seem to hold a higher value than the 454. Anyone know why? It making me a little nervous now and I am supposed to buy the boat in the morning. Is there a history of problems with this engine?
