Polipodio 2626208 OMC Cobra 983952 / 984547 Lower Block Zinc Plate Anode 130–385 HP
The Polipodio 2626208 is a zinc sacrificial plate anode designed for the lower block of compatible O.M.C. Cobra marine propulsion systems rated from 130 to 385 HP.
The manufacturer's catalogue identifies original replacement references 983952 and 984547. An additional Trem listing associates the related Polipodio OM009 and Trem L8142001 references with O.M.C. Cobra applications.
The anode features a profiled rectangular body with mounting holes and recessed areas. The manufacturer's drawing indicates an overall width of 120 mm and an overall height of 109 mm.
Manufactured from zinc, the anode provides sacrificial galvanic corrosion protection for electrically connected metallic components exposed to water in compatible propulsion installations.

OMC Cobra Compatibility
The Polipodio 2626208 is listed for compatible O.M.C. Cobra lower block applications in the 130–385 HP range.
The supplied original replacement references are:
- 983952
- 984547
The related Trem catalogue lists the zinc anode under model FG-8, with Polipodio reference OM009 and original code 983952.
The supplied information does not identify individual Cobra drive versions, production years or serial number ranges. The power range alone does not guarantee compatibility with every installation.
Confirm the original part number and mounting geometry before ordering.
Lower Block Anode Dimensions and Mounting
The Polipodio 2626208 features a shaped plate body with recessed sections and mounting holes.
The supplied manufacturer's drawing identifies:
- Overall width: 120 mm
- Overall height: 109 mm
- Lower fixing-hole centre distance: 75 mm
- Vertical mounting measurement: 55 mm
- Circular fixing holes shown: 3
- Additional sectional dimensions: 20 mm and 10 mm
The sectional measurements of 20 mm and 10 mm relate to individual features shown in the side profile. They do not establish a complete overall thickness measurement.
The diameters of the circular fixing holes have not been specified. Compare the replacement with the original anode and verify all mounting dimensions before installation.
Zinc Sacrificial Corrosion Protection
The Polipodio 2626208 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, zinc corrodes preferentially, helping reduce galvanic corrosion of electrically connected components exposed to water.
Material suitability and replacement intervals should be determined according to the operating water conditions and the propulsion equipment manufacturer's maintenance recommendations.
Polipodio and Trem Cross-References
The following references appear in the supplied catalogue information:
Reference Description Polipodio 2626208 Zinc plate anode, O.M.C. Cobra lower block Polipodio OM009 Related reference identified in Trem catalogue Trem L8142001 Zinc anode for Bombardier / Johnson / Evinrude / O.M.C. Trem FG-8 Model designation 983952 Original replacement reference 984547 Original replacement reference
Trem L8142001 EAN: 8024827646472
The Trem listing associates OM009 and L8142001 with original reference 983952. However, identical construction and complete dimensional interchangeability with Polipodio catalogue article 2626208 have not been independently confirmed.
Inspection and Replacement
Inspect the lower block anode periodically during routine O.M.C. Cobra drive maintenance. Replace it when the sacrificial zinc becomes significantly depleted, damaged or no longer securely mounted.
Before fitting a replacement:
- Confirm the O.M.C. Cobra drive configuration.
- Check original part number 983952 or 984547.
- Verify the 120 mm width and 109 mm height.
- Compare the original mounting-hole layout.
- Check the 75 mm and 55 mm mounting measurements.
- Inspect the mounting contact surfaces.
- Follow the applicable propulsion equipment manufacturer's installation instructions.
