MG Duff CM6E54537101Z Yamaha 150–200 HP Skeg Trim Tab Zinc Anode Ø92 × 76 mm

The MG Duff CM6E54537101Z is a zinc sacrificial skeg trim tab anode designed for compatible Yamaha 150–200 HP outboard motors. Manufactured from zinc, it is intended for saltwater applications and helps protect electrically connected underwater metallic components against galvanic corrosion.

The anode measures 92 mm in outside diameter and 76 mm in height, with an M10 × 1.25 mounting thread. Its specified weight is 0.42 kg (420 g).

Technical Specifications

Yamaha Outboard Compatibility

The MG Duff CM6E54537101Z is listed for Yamaha outboard motors in the 150–200 HP range requiring this skeg trim tab configuration.

Specific Yamaha engine model numbers, production years and original equipment part numbers have not been provided. Engine horsepower alone does not guarantee fitment, so the existing anode should be checked before ordering.

Skeg Trim Tab Dimensions and Mounting

The CM6E54537101Z features the following specified dimensions:

• Outside diameter: 92 mm
• Height: 76 mm
• Mounting thread: M10 × 1.25
• Weight: 0.42 kg

The M10 × 1.25 designation specifies a metric thread with a nominal diameter of 10 mm and a pitch of 1.25 mm.

Before installation, compare the replacement with the original skeg trim tab and verify the mounting configuration, dimensions and thread specification.

Zinc Sacrificial Corrosion Protection

The MG Duff CM6E54537101Z is manufactured from zinc, a sacrificial anode material commonly used in saltwater marine environments.

When correctly installed with suitable electrical continuity to the metallic components requiring protection, the zinc corrodes preferentially, helping reduce galvanic corrosion of electrically connected underwater outboard components.

The suitability of zinc should be confirmed according to the operating water conditions and Yamaha's maintenance recommendations.

Inspection and Replacement

Inspect the skeg trim tab anode periodically during routine Yamaha outboard maintenance. Replace it when the zinc becomes significantly depleted, physically damaged or no longer securely attached.

Before fitting a replacement:

• Confirm the Yamaha outboard model and original trim tab configuration.
• Verify the 92 mm outside diameter.
• Check the 76 mm height.
• Confirm the M10 × 1.25 mounting thread.
• Inspect the mounting surfaces and follow the applicable Yamaha installation instructions.
