Bilge pump mounting position
Silly question time but hey, the only silly ones are the ones you don't ask, right?
Rule bilge pumps, is there any reason why you can't mount them horizontally? the exit route for the pipe and various other things are easier in this orientation although I know that I won't get the sump quite empty I am not too bothered about that.
Just want to make sure that they are not designed to run in the remains of the bilge water and running it completely dry on its side will not bugger it up.
