Flex Length per NEC


I was intending to install only 6 feet of 3/4 non metallic flex (grey pLastic/pvc) but I thought I read somewhere here that the length is not necessarily limited to 6 foot.
I would like to install 25 feet of flex under my deck from house (gfci panel) to spa control panel.
I will have 3-#6 in the cable---for 60 amp 220 to a Sundance Optima.
Is that ok?
what would be the "support" requirements?

The disconnect from the spa is what matters. I would just run the Schedule 40 under the deck, paint it after you get it hung, the color of the deck, then place the disconnect within six feet of the spa.

You are allowed 6 ft outside the spa, plus the amount under the spa.

No problem. Just remember to leave a drip loop under the disconnect, where you run the flex into it.

You know the second I read your advice--"drip loop"---I visualized a "P" trap----and water dripping from the lo point---thank you again---I will do that!
