Do not buy a "525SC" or any other boat with a supercharger on it for just recreation.
The words TEMPRAMENTAL is putting it mildly. Bitchy is more accurate.
On the Great Lakes (I run on Lake Ontario) the temperature/barometer swings from day to day and tuning the boat for every use is just not practical. A buddie had a 42' Motion cat with a couple of 525sc's in it. 110+ mph is fast but he had to do a couple of hours of work for a few hours of play.
I can empathize with the idea of a "blower" but I believe that you would be better served with the EFI motors.
