HOw can I trick the thermostat on my Marquis Spa, so that I can heat
the water to higher than 104 degrees?

(Marcia got someone to do this, and it worked :-)

Who is this Marcia chick? She must be hot.


I'd suggest seeing what service manuals, schematics, etc might be
available from the manufacturers websites. There may not be any, but
it's worth a shot. I have an older spa and inside the controller pack
on mine there are pots that adjust the temp calibration. I would
suspect many of them would have this.

If that fails, putting some insulation material over the temp sensor
might work.
