Since we are now in an era of new outboards
and modified ob wells -
perhaps a better determination of optimum prop depth
would be from the waterline on the Ariel
or Commander
to the center of the prop.
Thus, 'the center of my prop is 6" below the designed waterline on my Ariel
and it doesn't cavitate in a chinese chop.'
338's high thrust Yamaha 4/8
is 16" below the D,W,L,... and it doesn't cabitate neither,
but it's not in the water
yet.
