this is my first boat, and am excited about it. only prob is i dont know a whole lot about em. for one thing, we were drivin in the marina for about 35 min, then the motor died out. so the guy selling it to me tried to start it up, but to no avail. it sounded as if you would turn the keys in the car then would almost turn over. after 20 min the boat started up again. the engine sounds beautiful, the acc work and everything. does anyone have an idea of what the problem might be
