The load of the engine weight is cantilevered off the transom, producing especially acute bending forces on the transom when the boat is bouncing down the highway on a trailer. With long setbacks, it may not be feasible to support the lower unit(s) of the engine(s) with an auxillary load bar, as is often done when trailering an engine in the tilted-up position. Stress on the transom from the large unsupported engine weight can be considerable.

They haven't seen MJ's contraption. :o ;D
