That's intresting. I have yet to run my cat but I have expected that take off cavitation would not be a broblem because the prop would be completely submerged. I have this problem with the SV27 but there are wierd flow patterns around the transom and the top blade is out of the water pretty fast. With a cat I'd expect that this wouldn't be a problem. That is a small prop for a 26" boat IMO.
