NO! Since all lower units that I know of have drive dog clutches, when put in either gear, the prop will rotate a little bit freely then either lock up or ride up the back ramps and drop back with a click. Think about two sets of saw teeth opposed to each other. One way they will lock and the other way they will ride over each other before nesting together again.
