Its a long time since I flew. a 737, ( 200 and 300) but is it the case that the Max system is capable of driving the stab. to FULL deflection .
Time dims the memory but IIRC. The 73 75 and 76 and other types I have flown, that was not the case, in fact stick pushers only moved the elevators, stabs were not moved.
Surely switch direction of the stab trim cutout switches is irrelevant, if something is ON. to switch OFF. Simply move the switch(es) away from that position !
