Marine-grade aftermarket flat, low-profile trim tab anode for selected 35–300 HP Mercury / Mariner outboards and MerCruiser Alpha One Gen II and Bravo sterndrives.

Designed to provide additional clearance for high-rake propellers where a conventional finned trim tab could interfere with the propeller.

Helps protect the gearbox and underwater metal components against galvanic corrosion.

Main Part Number: 76214-5

Available in Zinc or Aluminium.

Important Compatibility Information

Please confirm:

• Engine horsepower, model and serial number

• Gearbox or sterndrive model

• Original trim tab configuration

• Diameter and mounting thread

• Propeller clearance

• Required anode material

If the part looks the same as yours, this does not always mean it is the correct part for your outboard or sterndrive.

A flat anode does not provide the steering torque adjustment of a finned trim tab.
