Mercury 30/40 HP fin anode – code: 5123017 – Motomarine

Mercury 30/40 HP fin anode – code 5123017 (Motomarine)

The’fin anode Motomarine with code 5123017 is a spare part designed for the maintenance of Mercury outboard engines in the indicated power ranges. It is a consumable component used in the nautical field to protect metal parts exposed to the marine environment and galvanic currents, helping to keep the engine group efficient over time.

This version is suitable for applications on Mercury 30/40 HP and, according to the product description, also for 25–50 HP (4T). When purchasing, it is good practice to always verify the correspondence through code and configuration of your engine.

Product identification

• Product: Fin anode
• Recommended application: Mercury 30/40 HP
• Further indication in description: 25–50 HP (4T)
• Supplier product code: 5123017
• Supplier: Motomarine S.R.L.

Spare part for scheduled maintenance

Anodes are among the components that, by their nature, are subject to wear. Regular checks allow intervention before wear becomes excessive, maintaining adequate protection of the engine's metal parts. In case of doubts about the anode's condition or correct application, it is advisable to consult a technician or your service center.

Typical applications

This fin anode is intended for Mercury outboard engines in the power ranges indicated by the description. It is a spare part used in contexts of:

• Routine maintenance outboard maintenance, particularly before or after prolonged periods of use.
• Storage and seasonal checks, when inspecting components subject to wear.
• Restoration interventions on engines that have operated in marine environments or in waters with high aggressiveness.

The wording present in the existing description also includes the indication 30–40 HP (2 cyl 2T) e 25–50 HP (4T). Since variants may differ, it is recommended to use the code 5123017 as the main reference for verification.

Operational advantages

• Support for the protection of exposed metal parts, reducing the impact of galvanic phenomena.
• More organized maintenance: the anode is a dedicated and replaceable component, useful for targeted wear management.
• Risk reduction of deterioration of more critical components, thanks to the presence of a “sacrificial” element.
• Identifiable spare part via supplier code, useful for reordering and managing spare parts onboard or in the workshop.

Inspection and replacement

• Periodic inspection: check the condition of the anode during routine engine inspections.
• Replacement when necessary: if the anode is worn or deteriorated, it should be replaced to maintain protection.
• Check for proper contact: an anode must be properly installed to perform its function; if in doubt, rely on qualified personnel.

Compatibility: how to check before purchase

Compatibility can depend on multiple factors. For an informed purchase:

• check that the requested spare part corresponds to the code 5123017;
• compare the indicated application (Mercury 30/40 HP and additional indication 25–50 HP (4T)) with your engine data;
• if available, consult the spare parts diagram or the engine technical documentation.

Notes for nautical contexts

In a marine environment, galvanic corrosion can be influenced by many variables (type of water, time in water, presence of other metals, onboard electrical system). For this reason, it is useful to complement the anode replacement with a general check of the engine and exposed metal components.

Summary

The’Mercury 30/40 HP fin anode Motomarine code 5123017 is a spare part dedicated to the maintenance of outboards in the indicated power ranges, useful for proper management of the protection of metal parts. For the correct choice, always refer to the code and the specifications of your engine.
