Installation Notes

1. For safety, disconnect the engine's battery cables before beginning work. Tilt the outboard to the full "up" position to access the lower unit.
2. Locate the existing trim tab anode, which is typically found on or near the anti-cavitation plate.
3. Use a socket wrench to remove the mounting bolt securing the old anode. The bolt may be corroded, so apply penetrating oil if necessary.
4. Thoroughly clean the mounting surface on the lower unit to ensure a good electrical connection. Remove any corrosion, paint, or marine growth.
5. Position the new trim tab anode and insert the mounting bolt. Tighten it securely according to the manufacturer's torque specifications, if available.
6. Lower the engine and reconnect the battery. Check the installation before operating the vessel.
