Electromechanical control circuit for causing trim tabs attached to the stern of a hull of a motorized marine vessel, and used to trim the attitude of the vessel, to be automatically fully retracted by activating means independently of the boat ignition switch to cause a capacitor in the circuit to discharge. The means can include at least one switch connected between the capacitor and an electrical power source to which the control circuit can be connected such that the means are activated when the switch is opened. The switch can be positioned at multiple locations throughout the boat or, alternatively, controls to cause the switch to open can be mounted to the boat at multiple locations throughout the craft, including at the main control panel. The means can also be in communication with boat engine gear shift controls such that the means are activated when the vessel engine is shifted into reverse gear. The control circuit further includes means for preventing damage to the circuit components if the circuit is improperly connected to the electrical power source.
