This guys a stroker. I do this for a living and have never had someone ask to bring the boat to them. Tell him to come to you to look at the boat and test run it. If he buys it you will pay for his hotel and deliver the boat within a week. This is the way I have done it with my customers and those of my salespeople for 10 years.
Worst case is no deal. Best case is you are out another 200 or 300 bucks.
