Your question makes sense but I would first ask if you are sure you’re getting 25-30mph out of the air prop? I would say you should be able to use a similar set up with a larger ESC to be safe and get equal if not better performance with a water prop. The water prop should be more efficient at producing thrust because if it wasn’t most all full scale boats would be air driven not water driven. My $.02 for what it is worth.
