Thanks for the clarification Peggy. I'll check the ratings on the hot tub
hose and let you know what I come up with.
I would imagine that if I can get the manufacturers part #s at the hardware
store, I could compare with #s on marine hose.

I saw hose that looked

the other day and when I asked the salesman about it he said it was hot

convince me to try it next time.

You'll be sorry. Not all white flexible pvc hose is created equal...and
hot tub hose is not rated for sanitation system use, only for water use.
It'll permeate with odor very quickly.

I've also found tygon (sp?) tubing with the colored reinforcements and
all
at a farm supply for alot less than boat store people sell it for.

That may be ok, but if it'll be connected to any below-waterline
thru-hulls, make sure it's a grade that's rated for below-waterline use.

Flex hoses are like hard PVC in that they have "schedule" #s...schedule
148, 144 and 101 are rated for sanitation use...I'm not sure what the
"schedules" are for clear hose, but they also use a standardized system
that will tell you which hoses are rated for below waterline use and
which ones aren't.
