Just for the sake of conversation, one possible exception to that might be an exceptionally heavy slow boat where the extra surface area of the second prop MAY reduce slip% enough to increase speed or even plane where otherwise it wouldn't...
I've sen where twins gave more speed than a single of the same combined hp due to the fact the twins were able to provide more lift to the hull, its rare, but I've seen it
