I am considering buying a 2004 Sea Ray 240 Select from a boat dealer. Here is the situation, they told me the engine was recently replaced by Merc due to water damage. While it has 0 hours, I am concerned there are other issues. What other things should I be worried about? Is this a big enough red flag to not buy the boat? How does this affect the overall value of the boat on the market. The boat is for sale for 45k and based on my research it appears to be overpriced by 10k. Thanks in advaced.
