Appreciate the input from both of you. I am thinking that there might be something to the false alarm thing but we don't have a lot of things to mount on. The galley is made up of a lot of individual components that fit together with spaces of about 1/2 to 1/4 inch between them - basically inaccessible
The bilges on the boat are the shallowest I have ever seen - the deepest part of the bilge is right in the center of the cabin, and it is 4 inches deep, so there is not enough space to put a sensor, as they cannot get wet.
So I guess I'll go a little further from the stove and maybe stick it inside the locker under the sink - about 6" up from the hull.
Does anyone know how much propane it takes to blow up a boat ??? (seriously)...
