Understanding Bennett Trim Tabs
Bennett trim tabs are designed to enhance the performance of your boat by allowing you to adjust its attitude while underway. These tabs are mounted on the transom and can be raised or lowered to improve stability, handle rough waters better, and increase fuel efficiency. The operation of these trim tabs is controlled by a rocker switch, which is typically located on the helm.
Components of the Bennett Trim Tab System
Before diving into the wiring diagram, it’s important to familiarize yourself with the primary components of the Bennett trim tab system:
1. Rocker Switch: This is the control mechanism that allows the operator to raise or lower the trim tabs.
2. Trim Tabs: These are the actual adjustable flaps mounted on the transom of the boat.
3. Actuators: These are the electric motors that move the trim tabs up and down.
4. Wiring Harness: This connects all the components, providing power and control signals.

3. Mount the Rocker Switch: Choose a suitable location on the helm for the rocker switch. Use a drill to create a hole if necessary and secure the switch in place.
4. Connect the Power Supply:
- Connect the red wire from the power source to the top terminal of the rocker switch.
- Connect the black wire to the ground terminal.
5. Connect the Actuators:
- Connect the blue wire to the terminal on the rocker switch designated for the up function.
- Connect the green wire to the terminal designated for the down function.
6. Connect the Actuators to the Trim Tabs: Run the wires from the rocker switch to the trim tab actuators, ensuring that they are properly secured and protected from water exposure.
7. Test the Connections: Once all connections are made, turn the power back on. Use a multimeter to check for continuity and ensure that the switch properly activates the actuators.
8. Secure and Seal: Once confirmed that everything works correctly, secure all wires with electrical tape and ensure that connections are waterproofed.
Common Troubleshooting Tips
If you encounter issues with your Bennett trim tab system, here are some troubleshooting tips to consider:
