Note on measurements

In case of replacement, it is good practice to compare shaft diameter e main dimensions (A, B, C, H, F) with the installed anode or with the technical drawing of the component. If the application involves tolerances or particular configurations, always verify the correspondence before purchase.

Typical applications

• Maintenance and replacement of anodes on shafts in the nautical field
• Interventions on propulsion components and metal parts subject to corrosion
• Replacement for onboard systems where a collar anode with the indicated dimensions is required

Advantages

• Collar format practical for replacement in scheduled maintenance
• Clear identification through Motomarine code 5150025 and available dimensions
• Material in zinc suitable for nautical use according to common galvanic protection practices
• Facilitated dimensional control thanks to weight and measurements reported in the datasheet

Use and maintenance notes

The correct effectiveness of an anode depends on installation, electrical contact, and operating conditions. Below are some general guidelines useful during assembly and inspection, to be understood as good practices and not as instructions replacing the boat or component manual.

Before installation

• Check that the’shaft is Ø 25 mm and that the dimensions of the anode are consistent with the available space.
• Check that the contact surface is clean and free of oxides or residues that could reduce contact.
• Compare the code 5150025 with the spare parts list or with the removed anode.

During assembly

• Place the collar in the designated seat and ensure that the fit is stable.
• Avoid damaging the surface of the anode during tightening and handling operations.

Periodic checks

• Visually inspect the anode during routine maintenance: wear is a useful indicator of consumption status.
• If the anode is worn or no longer efficient, plan replacement with an equivalent spare part in material and dimensions.

Practical advice

When possible, keep the removed anode and note the main dimensions: it facilitates the identification of the correct replacement in the future, especially when similar size variants are present.
