A few questions regarding my new "used" Grady. How or where is the refrigerator powered from? The Port engine raises fine but the Starboard engine labors a bit while raising or lowering. Could there be air in the trim/tilt system? The engines also flop over to the Port side while in the raised position. I have noticed salt water about 4" after 3 or 4 days accumulating in the forward bilge compartment and also the presence of sand in there as well. I am not ready to haul the boat out just yet but was wondering if anyone might have some ideas on these questions. Other than these minor issues we are very satisfied with the boat.
