Very interesting, especially as the 3-view drawing shows a mix of 3 and
4-blade props. I wonder why this would be?

The two inner engines were fitted with four-bladed reversible pitch
propellers; the outer engines had standard three-bladed feathering props

Do you know why? Was this for enhanced maneuverability on water?



Just as a wild guess...

It may be that the outboard engines get shut down in flight?
Seaplanes need a LOT of power to get off the water.
But not that much for cruise.
