well for anyone that has to change out digital controler on a marquis tub 1996-1999 can use a balboa 54094 it looks differnt oval vs square but hole under is the same no cutting just caulk around controler under where face meets tub just to be safe and plug it in turn on power and your all set to go works great and saves a lot of time of finding one or trying to match one up and i hope this helps someone out
