It could be like in Mich. you have to load your boats without the big motor. I just bought a boat in Mich. and after running it I was getting ready to load it and There was a sign saying no power loading. You get fined if you drive your boat on the trailor. the guy I bought it from told me that you weren't allowed to drive the boat on in any of the lakes in Mich. because it washes away the ramps.
