1. Introduction
The Bennett Marine A1103 Upper Hinge is a genuine replacement component designed for use with Bennett Hydraulic Trim Tab Systems. This hinge serves as a critical connection point, securing the upper portion of the trim tab actuator to the boat's transom. Its proper function ensures stable mounting and contributes to the smooth and effective operation of your vessel's trim tabs, allowing for optimal boat performance and control.
2. Setup and Installation
2.1 Before You Begin
- Ensure the boat is out of the water or the trim tab system is safely accessible.
- Gather necessary tools, which may include wrenches, screwdrivers, and marine-grade sealant.
- Confirm the replacement part is the correct A1103 Upper Hinge for your Bennett system.
2.2 Installation Steps
- Remove Old Hinge: Carefully disconnect the trim tab actuator from the existing upper hinge. Remove any fasteners securing the old hinge to the transom.
- Clean Mounting Surface: Thoroughly clean the transom surface where the new hinge will be mounted, removing any old sealant or debris.
- Apply Sealant: Apply a marine-grade sealant to the mounting surface and around the fastener holes to ensure a watertight seal.
- Position New Hinge: Align the new A1103 Upper Hinge with the existing mounting holes on the transom.
- Secure Hinge: Install marine-grade fasteners through the hinge and into the transom. Tighten fasteners securely, but do not overtighten.
- Reconnect Actuator: Reattach the trim tab actuator to the newly installed upper hinge, ensuring all connections are secure.
- Test System: After installation, test the trim tab system to ensure proper movement and alignment.

3. Operation
The A1103 Upper Hinge is a static component that facilitates the dynamic movement of your trim tabs. Once installed, it provides the pivot point for the trim tab actuator, allowing the trim tab to move up and down. Proper installation ensures that the hinge allows for the full range of motion without binding, which is essential for the trim tab system to effectively adjust the boat's running attitude. The hinge itself does not require direct user operation but is integral to the overall system's functionality.
4. Maintenance
Regular maintenance of your A1103 Upper Hinge is crucial for ensuring the longevity and reliable performance of your trim tab system, especially in harsh marine conditions.
- Routine Inspection: Periodically inspect the hinge for any signs of wear, corrosion, cracks, or damage. Check for loose fasteners.
- Cleaning: Clean the hinge and surrounding areas regularly to prevent salt buildup and marine growth. Use fresh water and a mild soap, then rinse thoroughly.
- Fastener Check: Ensure all mounting fasteners remain tight. Do not overtighten, as this can damage the hinge or transom.
- Corrosion Prevention: If the hinge is exposed to highly corrosive environments, consider applying a marine-grade anti-corrosion spray or grease to the metal components, if applicable and recommended by Bennett Marine.
