![Restore Your Vintage Marquis Spa with the MTSICD Circuit Board 600-6246
The Marquis MTSICD Circuit Board (Part# 600-6246) is a genuine Balboa-engineered replacement built to bring 1990s-era Marquis spas back to full working order. If your control system is failing, this hard-to-find board could be exactly the fix you need.
[Shop and order at Western Tub and Pool]
Why This Circuit Board?
Built for Precision Compatibility
Identified by chip number MTSICDR1A, not just its appearance—so you can be confident you're getting a board that actually matches your spa's software and function, not just one that looks the part.
Trusted Balboa Engineering
Cross-referenced to Balboa Number 53092, this board carries the reliability of one of the spa industry's most established control system manufacturers.
A Genuine Hard-to-Find Part
This board has been discontinued by the manufacturer, making sourcing a genuine replacement difficult. We stock and source these parts specifically because we know how hard they are to track down.
Backed by Real Support
Not sure if this is the right board for your spa? Our team is on hand to help you confirm fitment before you buy.
Compatible Hot Tub Models
The Marquis MTSICD Circuit Board 600-6246 is used in the following models:
1995 Mirage MTS I
1995 Quest MTS I
1995 Retreat MTS I
1996 Retreat MTS
1996 Quest MTS
Always confirm your chip number (MTSICDR1A) or Balboa number (53092) before ordering, as several boards share a similar appearance but run different software.
Associated Repair Parts
Circuit board replacements are often paired with the following components. Check our online catalogue or call us to see if you need these alongside your board:
Balboa Temperature/Hi-Limit Sensor Assembly
Marquis Spa topside control panels
Spa heater assemblies
Not sure what else your repair needs? Send us your make, model, and serial number and we'll help you build the full parts list.
Common Questions
How do I know if this is the right board for my spa?
Don't rely on looks alone. Check the white sticker near the center of your existing board for the chip number (MTSICDR1A) or look for the five-digit Balboa number (53092). If either matches, this board is a fit for your 1995–1996 Marquis Mirage, Quest, or Retreat MTS I model.
Is this board new or used?
We carry both new and remanufactured boards depending on availability, as this is a discontinued part. Contact us at fixmytub@gmail.com to confirm current stock condition before ordering.
What are the dimensions and weight of this board?
Circuit board dimensions and weight can vary slightly by production batch and region of origin. Contact our team with your part number for exact specifications, or send us a photo of your existing board for confirmation.
What if I can't find my exact part number?
Send us a picture of your current board along with your hot tub's make, model, and serial number. Our team will identify the correct replacement for you.
Do you ship internationally?
Yes. As an international e-retailer, we source parts from warehouses around the world. Because of this, Western Tub and Pool uses regional suffixes to identify part origin:
U – USA
C – Canada
E – Europe
A – Asia
Some parts may be duplicated across regions, so your order may ship from the warehouse closest to you.
Struggling to Find the Right Part?
Hard-to-find spa parts are our specialty. If you're not sure which board, sensor, or panel your spa needs, email us at fixmytub@gmail.com with pictures, your hot tub's make and model, and the serial number if available. We'll help you track down the exact match.

Why This Board Is the Right Fix
Genuine OEM Quality: Manufactured by Balboa for Marquis spa systems, this is a brand-new, factory-original board—not a generic aftermarket substitute.
No Pressure Switch Needed: Built on the VS501Z platform with Balboa's M7 technology, this board handles temperature and water flow sensing without a separate pressure switch, meaning fewer parts to fail down the line.
Full-Function Control: Runs your 2-speed primary pump, 1-speed secondary pump, 12V spa light, and ozonator, so every feature of your spa stays operational.
Confirmed Compatibility: Covers a wide range of 2006 and 2007 Marquis models, plus every 2008 Marquis spa, so there's a strong chance this is the exact board your tub needs.
Direct Upgrade Path: This board replaces the older 600-6288, so if your spa used that part, 600-6293 is your drop-in solution.

This board is confirmed compatible with the 650-0635 topside panel. If your spa uses a different topside, contact us before ordering to confirm fit.
Is this board new or refurbished?
This is a brand-new, factory-original board that has never been installed.
Can I return this part if it doesn't fit?
Circuit boards are non-returnable once purchased, so please confirm your chip number, spa model, and year with our team before placing your order.

As an international e-retailer, Western Tub and Pool sources parts from warehouses across multiple regions, which can affect shipping times. To help you identify where your part ships from, we've added regional suffixes to our part numbers: U for U.S.A., C for Canada, E for Europe, and A for Asia. Because of this, you may see what looks like a duplicate listing for the same part—this simply reflects a different regional warehouse.
