I bought a 2005 Utopia 205 with the 250 Optimax in excellent condition with most of the upgraded options this past spring. I paid $15,000 for it on a trailer which was, according to my research, the mid to low end pricing on NADA and also compared to others for sale around the country. We absolutely love the boat and had alot of help from the folks on this forum...thanks again!! After the first weekend on the water pulling tubes and wakeboards it would stall out intermittently. Found it to be fouled plugs, was told way too many idle hours on the motor which we took care of this summer! I was nervous it was a much bigger issue, thankfully it wasn't and the boat has been a hell of alot of fun!
My lack of buying experience and being in a hurry could have really cost me alot of money but so far we have been blessed. When I went out with the seller for a test drive, he didn't let me drive it and we were only out for about 30 minutes, 20 of those were getting from his dock, down river to the lake and back again, and never getting up to full throttle. So for what its worth, I will insist on a good 20-30 minute run on any boat I ever buy and I will drive it or no deal. Also, I am not a mechanic so I will always have a certified inspection done.
My guess is alot of you may already know and do these things when buying a used watercraft, but maybe other first time buyers may get some help from my experience!
