Most of the feathering props are 'pitch adjustable' .... some can either have their pitch adjusted while the prop is still installed and the boat is IN the water. With most feathering props, you can OPTIMIZE the prop's pitch to optimized engine rpm for best power/efficiency,etc.
Folders while having much better drag characteristics, cant be easily pitch adjusted.
