was thinking of mashing inside and sparging outside.
That should be fine.
save the propane for the boil by doing mash on stove.
Also fine.
then mixing it with sparge water on the burner. will that work?
So you are going to use the burner to heat the sparge water? Or not. It doesn't matter, what you're saying is that mash water and sparge water will be combined into your boil, which will be outside on your propane setup. Okay, that's all good.
will leaving the flame on low prevent most heat loss?
When we did the mash outside on my buddy's propane, just a 1 min. burst of propane two or three times an hour was good enough to keep the temp up. I think if you keep the propane on low you will actually overheat your mash.
also will i be alright doing a 5 gallon boil in a 7.5 gallon pot?
Yes, provided you do one of three things:
1) mount a fan to blow on the surface of the liquid constantly
2) fill a spray bottle with cold water and watch for boilovers like a hawk
3) add Fermcap-S to the boil
Fermcap-S is proof that there is such a being as the "Beer Fairy". It is *magical*.
