Frequently Asked Questions
How do I know if the 600-6219 board is right for my spa?
Check your existing circuit board for the part number 600-6219, or look for the MTSIR1F chip designation. If your spa is a 1994–1996 Mirage, Retreat, Oasis, Escapade, Voyage, or Serenity model, this board is likely a match. Still unsure? Send us a photo of your current board along with your spa's make, model, and serial number, and we'll confirm fitment for you.
What's the difference between this board and other Marquis circuit boards?
Marquis produced several circuit board variations across model years and control systems (MTS I, MTS II, HPSL, and more). The 600-6219 is specific to MTS I/MTSL systems using the MTSIR1F chip. If your spa uses a different chip or control system, you'll need a different board—our team can help you identify the correct part.

Frequently Asked Questions
How do I know if the 600-6219 board is right for my spa?
Check your existing circuit board for the part number 600-6219, or look for the MTSIR1F chip designation. If your spa is a 1994–1996 Mirage, Retreat, Oasis, Escapade, Voyage, or Serenity model, this board is likely a match. Still unsure? Send us a photo of your current board along with your spa's make, model, and serial number, and we'll confirm fitment for you.
What's the difference between this board and other Marquis circuit boards?
Marquis produced several circuit board variations across model years and control systems (MTS I, MTS II, HPSL, and more). The 600-6219 is specific to MTS I/MTSL systems using the MTSIR1F chip. If your spa uses a different chip or control system, you'll need a different board—our team can help you identify the correct part.
Do you ship internationally?
Yes. Western Tub and Pool is an international e-retailer with warehouses across multiple regions. Because the same part may be stocked in different regions, we've added suffixes to indicate origin:

Please note that shipping times and costs vary depending on the regional warehouse your part ships from. Some products may be listed more than once if stocked in multiple regions.
