The amount of hours can vary a lot. I bought my boat when it was 10 years old with only 85 hours on it. Now 4 years later its only got about 100 on it. Im lucky to take it out 3 or 4 times a year. I know other guys on here who put 100 on in a single season.
Overall though, I agree with Pudder. Most the older boats have no hour meter and people pay good money for them all the time just because they look good. The newer boats could look just as clean or better and someone would shy away because it has high hours. Best thing to do is just make sure to do a water test and really check the boat out good. Ask the previous owner lots of questions. Ask about maintenance, ask for any receipts. Do a compression test on the engines. Doing your homework here ahead of time may prevent you form buying a POS. We see a lot of new people come on just because they just bought their first boat blindly with no guidance. Suddenly they find out its a pile of junk. A little time here can prevent that most of the time.
First thing to do is set a budget, then try to find the best thing you can for your price. ITs a good time to buy now till next spring prices will drop.
