ABSTRACT:
A twin lever control actuator (10) operates push-pull cables (17, 17a) and has two sets of pulleys (12, 12a and 13, 13a) on opposite sides of a control body (11). Interlock structure (120-124, 126, 128, 132, 134) normally prevents movement of the shift lever (14) and its cable (17) when the throttle lever (14a) and its cable (17a) are in a high speed position and with the operator applying normal force to the shift lever (14). Override structure (136, 148, 150, 152, 154) permits movement of the shift lever (14) and its cable (17) with the throttle lever (14a) in a high speed position when the operator applies an abnormally high force to the shift lever (14), to enable emergency high speed shifting including from forward to reverse, to facilitate rapid deceleration.
