Be intresting to see if the nose swings in /out in turns , as all the theorys would have us believe.
Personal intrest , as ive got a PC-7 (definately not politically correct > Piaago ) Flying Submarine (as it was called ) drawn up.
Just been loking at a magnificent Mc 39 that tragically DOESNT have floats. This doesnt either . It Has HYDOFOILS .
will need a similar shaft drive set up . No pinching the Pc7 idea . Sorry !
My theory is a light smallish prop , at steady revs will be the most satisfactory , the needley nose shouldnt impair the thrust.

Some radio flyer got a Pc7 working. electric water prop , clutched glow to airscrew. Full Size (1800 HP) had Dog Clutch Problems .
Very LOUD ones , I should think .
