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.
