I bought my boat new in 2002, Princecraft pro162 with a 40 4 stroke Mercury. I visited 3 dealers since I wanted new, one dealer was not interested in my buisness, the other did not have what i was looking and the 3rd dealer was great. If you buy new any reliable dealer will be willing to take you out for a test drive. Not many people buy a 20000$ car with taking for a drive so why should a boat be different. The web is a awesome tool to compare prices and what not and for research on particular makes and models. As far as motor models and makes. I love the 4 strokes, fill it up check the dip stick once in a while and you a set. Good luck on your search.
