Update on below post:
Well I think I have it figured out
The most important thing is that Spa Serial number.
Especially for an older model where many parts are obsolete.
Hi All -
Well I have a stumper, hope someone out there can help
Does anybody know what the manufacturer part number is for the Marquis 1997 Maximum Therapy Series Euphoria Spa Hydro Air Oval VSR Directional Jet? AND the part number for it's inserts, both directional and rotational. Marquis gave me the part number 320-6338 - which is I think round and dark gray. Balboa tells me it's an American Products part.
I have scoured the internet for days in online spa supply stores and cannot find exactly this item. Just the round dark gray one.
Attached is an image of what I'm looking for. The spa also has rotational jet inserts on another seat that are not spinning properly.
