Polipodio 976669 OMC 60–175 HP Zinc Alveolar Transom Bar Anode

Polipodio OM012 OMC 976669 60–175 HP Zinc Alveolar Transom Bar Anode

The Polipodio OM012 is a zinc sacrificial alveolar bar anode designed for the transom of compatible O.M.C. P60–175 HP outboard engines. It corresponds to original replacement reference 976669.

Manufactured by Enrico Polipodio, this anode features a curved bar profile with an alveolar, or cellular, body structure. It provides sacrificial galvanic corrosion protection for electrically connected metallic components in compatible outboard installations.

The manufacturer drawing specifies an overall length of 192 mm, a height of 43 mm and two fixing holes positioned 175 mm between centres. The fixing-hole diameter is indicated as 7 mm.

Technical Specifications

OMC Outboard Compatibility

The Polipodio OM012 is listed for compatible O.M.C. outboard engines in the P60–175 HP range requiring an alveolar transom bar anode corresponding to original reference 976669.

• Manufacturer: O.M.C.
• Listed Application: P60–175 HP
• Installation Area: Transom
• Original Reference: 976669

Specific engine models, production years and additional manufacturer references have not been provided. Confirm the original anode and the applicable engine parts documentation before ordering.

Alveolar Bar Design and Dimensions

The Polipodio OM012 features a curved sacrificial bar with a cellular, or alveolar, structure visible on the body.

The manufacturer's dimensional drawing provides the following measurements:

• Overall length: 192 mm
• Height: 43 mm
• Number of fixing holes: 2
• Fixing-hole centre distance: 175 mm
• Fixing-hole diameter: 7 mm

The 175 mm measurement identifies the centre-to-centre distance between the mounting holes, while 192 mm represents the overall bar length.

A separate body thickness and product weight are not specified in the supplied technical information.

Zinc Sacrificial Corrosion Protection

The Polipodio OM012 is manufactured from zinc, a sacrificial anode material commonly used for galvanic corrosion protection 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 metallic outboard components exposed to water.

The correct anode material should be selected according to operating water conditions and the propulsion equipment manufacturer's recommendations.

Inspection and Replacement

Inspect the transom bar anode periodically during routine outboard maintenance. Replace it when the sacrificial material becomes significantly depleted, damaged or no longer securely mounted.

Before fitting a replacement:

• Confirm the O.M.C. engine model and transom configuration.
• Check original reference 976669.
• Verify the overall length of 192 mm.
• Confirm the 175 mm mounting-hole centre distance.
• Check the two fixing holes and their 7 mm diameter.
• Compare the curved alveolar body with the existing anode.
• Follow the applicable manufacturer's installation instructions.
