Before you buy — quick checklist

  • Confirm your spa is a 2003 Marquis model using the MTSUV control system
  • Verify your existing topside has the oval shape and 6-button layout — do not assume based on year alone
  • Check the ribbon cable connector on your current topside matches this unit before ordering
  • Confirm your spa runs a Balboa control pack, as topside compatibility is control-pack specific
  • Inspect the topside port on your control pack for any corrosion or damage before installing a new panel

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
