quite a few prouts either elites or snowgooses carry 2 props with slightly different pitches,a finer pitch
for coastal waters and a courser pitch
for ocean passages.
sorry in Thailand
at the moment so cant quote exact size and pitch but think I have 12x17 and 12x19 which both work great and give about 7.6 knots with my 33hp motor
on my prout elite 37ft.
not sure if it would be possible to cut out the plate and fit a bigger prop without changing/extending the drive shaft
