I haven't seen your add till now, and thought I had seen them all in this size and range, but guess I haven't checked out Velocities really. Your boat looks real nice and like one hell of a deal. I think posting this question here is a good start in getting more views.
I personally don't think you should necessarily repaint the boat, unless you are a painter and can do it for cheap. I'm not a flames fan, but your boat looks nice, and most people into fast boats like something bright and standout. Paying for paint won't return much on the investment.
Your add is good too, but you could throw in some more scantily clad chick shots (probably won't help you sell, but we'd all appreciate it

)
The ebay idea I think is good for exposure and calls, and I don't think most deals are actually made through ebay, it's just more advertising.
Last, as someone who bought the house first and is now boat shopping, you are crazy. Seriously, there are much better investments than a house, and renting requires less upkeep and hassle. Not to mention the flexibility to move for better jobs, or whim, or whatever. I know houses seem like a bargain now, but I thought that in 06 in Detroit. Now I have a place with negative equity, and no damn boat (till spring anyways). So, if you really like boating, don't sell it. Keep renting, and take the extra house cost you were going to spend and invest it in mutual funds or something that are most likely going to earn you far more than a house, but minus the headaches and trapping you in a location.
Good luck.
