Don't think it would do much good as that is to far forward.. I have seen them installed just under the companionway entrance, usually by cutting out a little circle in the liner to gain access to the bilge area below. You can get a short pump and that will just sit flush with the liner. You could probably install an inspection cover to hide it if you got creative. I'm sure some H22 owners will chime in as to where they put theirs.. if they have one at all.
Cheers,
Brad
