What is the reason why they couldn't just turn a sterndrive around? These new jobbies would improve the handling being more inboard, but the theory could work with a reversed style sterndive leg? Or even an outboard as said before? No need for special hull and trailer etc.
I'm sure Volvo thought of all that though! I guess its because these new drives are built for gin palaces so are meant to replace shaft drives...perhaps
