I have a CD22 and a 90hp Suzi, 2008 (last year of the older style). The boat came with a three blade 14" dia, 19" pitch prop which I considered a bit too much as WOT only reached 5200rpm. I switched to a four blade 13.75" dia, 15" pitch prop which may be a tiny bit under proped for a light load but is more efficient at most speeds (up to 19 knots).
