This subject came up some years ago when I purchased my Newell. One of my valve covers labels says 450HP & the other says 500HP. Turns out there was a change in the type of fuel used in Gov't test back in the early 90's and most engines were downgraded from their original published HP. Regardless what I have, it is enough to go a fast as the tires allow.
Marine applications have a potential of substancially more power, but they also have a larger cooling ability, the bane of a detriot.
