ABSTRACT:
The present invention is a system for automatically controlling the trim of a boat drive thrust on a boat by controlling the trim motor which adjusts the trim angle of the boat drive thrust by pivoting the boat drive thrust relative to the boat. The system includes a control unit operatively coupled to the trim motor. The control unit causes the trim motor to adjust the trim of the boat drive thrust towards the horizontal when the control unit is activated. A trim sensor is provided on the boat drive thrust to measure the trim of the boat drive thrust. The trim sensor is operatively coupled to the control unit and is configured to send an activation signal to the control unit to activate the control unit when the sensor senses that the boat drive thrust is at a predetermined angle from the horizontal. The trim sensor consist of a pendulum movable between first and second electronic contacts, the sensor being configured to send the activation signal when the pendulum engages one of the electronic contacts. The trim sensor further includes a dampening mechanism for slowing the movement of the pendulum.
