I don't think I would give any more that that. I checked nada guides and it shows the boat worth 3600 and the motor worth 1300 and probably another 1000 for the trailer. Some people won't budge on the price though. They think its worth so much and aren't going to move. As long as you think your getting a good deal, thats all that matters.
Thanks! That's good info. I didn't think about looking for Nada. I guess it's like Kelly Blue Book for boats. I'm gonna offer 6k and see what happens.
