Interesting Adrian.....The piped OS 33 hauls the 20.5x10.5 prop pretty well at just about 7k. But most importantly is its ability to produce good mid range performance, with very good verticals on an 11 1/2 # plane.
It sounds like about the only subtle difference is downlines. While the two stroke's down line is plenty slow, it sounds faster. The four stroke's downlines not only look slow, they sound slow.
Thanks for posting honest assessments without hyperbole.....
