Location: champaign, illinois | My guess is the dealer is referring to the fact that outboard hp ratings used to be done at the crankshaft and now they are rating them at the propshaft. So in theory, the earlier higher hp rating is actually lower at the prop. Regardless, anytime you put a larger hp motor on a boat than it's rated for you most certainly will have liability and insurance problems. Not to mention if you get caught by the Coast Guard or any authority who has jurisdiction over such matters in your area.
Stay far far away from any dealer trying to pull that stunt!
