Unfortunately this is not true. And respectfully, your experience with your 250SS has nothing to do with the 200SS. I've tried many props now, talked to dealers that have done this repower, and the DF200SS is just not suitable for bass boats. Doss Marine in SC probably does the most Suzuki powers in the south east and they have been doing a ton of testing, and they can't break 62 mph, no matter what prop.
As Booter said, the torque curve is wrong, it doesn't have the power to turn a 24/25 prop in the upper RPM range.
