Finally got to try my boat! 2014 Z9 with 250 Pro XS. I am coming from a Tracker 2072 with a Mercury jet(modified jon boat hull) so the handling was crazy different. Everytime we accelerated it pointed way up in the air and once on plane at full throttle didn't want to go over 42 mph at a little over 4000 rpm. The trim gauge was off the end of the scale when the motor was all the way tucked in towards the boat. Does it need to be calibrated? It seemed to gain speed if I moved the motor away from the transom. This is my first boat over 25 horsepower other then the jet boat so I am on a steep learning curve. Thanks.
