Portable Propane Bottle Storage is Easy!
My 27 (OB in lazarette model) uses a 2 burner LPG stove (no oven) that uses the portable 1 lb. bottles that cost about $3-5 anywhere. I bought some 4" PVC pipe, about 10" long, and glued an end cap on one end. Then, with LONG hose clamps, I clamped it to the rudder post steering tube in the lazarette. There is a drain in the lazarette that goes overboard, so it's effectively vented. Its out of the way, doesn't interfere with the kick-up function of the outboard, easily accessible and can store 2-1 lb. bottles in tandem, which lasts about 2 weeks of cooking breakfast and dinner. I had previously clamped the same PVC setup to a stanchion, which also works, but found it was more in the way.
