What they probably do is use a different set of jets within the carb itself. If you can get to a set of schematics, you might be able to determine the different jet sizes needed. This will help in getting the extra HP, but I woudn't be too sure if there are not a couple of other things going on as well.... I wouldn't be surprised if there might be timing changes, exhaust tuner, etc...things that are not so apparent.
A good start on getting the boat to perform better is to get some baseline numbers...in your case, speed and prop specs. With that size rig, I would not be surprised if you did not have a tach, but if you do, that would be very helpful as well... From there, it might be just a prop change as was suggested.
