A 4hp motor has roughly 200 pounds of thrust. This force is directed normal
to the surface of the transom, in this mode the transom is the weakest.
Trailering a 50 lb motor puts the forces mostly in shear on the transom. In
this mode the transom is the strongest. For concerns about moment forces,
when the motor is down propelling the boat this has a much greater moment
than when the motor is raised in the trailing position (400 ft lbs vs 50 ft
lbs roughly). If you are concerned about the transom when trailering you
should also be more concerned about the transom when motoring the boat.
