Do an experiment and tell one dealer all the gory details and tell another one zilch and see where you get the better deal. that approach wont hurt and may help you.
In a way I did.
The guy I showed the picture offered the most help and said he will do what he can to get me the best price and under no terms would he push the sale of the boat with out me test running it and happy.
