Polipodio OM021 OMC Johnson Evinrude 431708 Zinc Plate Anode – Diabolo / FICHT RAM
The Polipodio OM021 is a zinc sacrificial profiled plate anode for compatible O.M.C., Johnson and Evinrude outboard propulsion systems. The supplied original replacement reference is 431708.
The manufacturer's catalogue identifies Diabolo 70–120 HP applications under article 2626220. The related Trem L8147311 product listing identifies FICHT RAM 135, 150 and 175 HP engines under the same original reference.
The anode features a rectangular, profiled plate with two recessed mounting holes. The manufacturer's drawing specifies an overall length of 75 mm, a width of 50 mm and a 40 mm fixing-hole centre distance.
Manufactured from zinc, it provides sacrificial galvanic corrosion protection for electrically connected metallic components exposed to water in compatible outboard installations.

The listed applications originate from separate catalogue descriptions. They should not be interpreted as universal compatibility with every engine between 70 and 175 HP.
Specific production years and serial number ranges have not been provided. Confirm the original equipment reference and mounting dimensions before ordering.
Profiled Plate Dimensions and Mounting
The Polipodio OM021 has a profiled rectangular zinc body with two recessed fixing holes.
According to the manufacturer's drawing:
- Overall length: 75 mm
- Overall width: 50 mm
- Fixing holes: 2
- Fixing-hole centre distance: 40 mm
- Additional sectional measurement: 20 mm
- Additional sectional measurement: 9 mm
The 20 mm and 9 mm values identify dimensions of individual features shown in the sectional view. They do not establish the complete overall thickness of the anode.
Fixing-hole diameters, product weight and fastener specifications have not been supplied.
Before installation, compare the original plate profile and mounting arrangement with the replacement anode.
Zinc Sacrificial Corrosion Protection
The Polipodio OM021 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 underwater outboard components.
Material suitability should be confirmed according to operating water conditions and the propulsion equipment manufacturer's recommendations.
Polipodio and Trem Cross-References
Reference Description Polipodio OM021 Zinc profiled plate anode 2626220 Catalogue article 431708 Original replacement reference Trem L8147311 Related zinc anode listing
Trem L8147311 EAN: 8024827645277
The Trem listing specifies Polipodio OM021, original code 431708 and FICHT RAM 135 / 150 / 175 HP applications.
The Trem article and EAN are included for cross-reference searches. Packaging and full dimensional interchangeability between catalogue listings should be verified if necessary.
Inspection and Replacement
Inspect the zinc plate anode periodically during routine outboard maintenance. Replace it when the sacrificial material becomes significantly depleted, physically damaged or no longer securely mounted.
Before fitting a replacement:
- Confirm the O.M.C., Johnson or Evinrude engine model.
- Check original replacement reference 431708.
- Verify the 75 × 50 mm body dimensions.
- Confirm the two-hole mounting arrangement and 40 mm centre distance.
- Compare the recessed mounting profile with the original anode.
- Follow the applicable manufacturer's installation instructions.
