Sealkit-OBM – code: MC26-816575A2 – Mercury

Sealkit-OBM Mercury – code MC26-816575A2

The Sealkit-OBM Mercury with code MC26-816575A2 is a gasket kit intended for maintenance and restoration activities on Mercury/Mariner and MerCruiser components, in the nautical field. It is offered as original Mercury Marine spare part (OEM), intended for those who wish to maintain consistency with original equipment components and manage repairs with officially sourced spare parts.

In a technical context like onboard, a gasket kit is often the most practical choice when performing disassemblies, overhauls, or replacements: it allows having the necessary sealing elements available to properly reclose an assembly, reducing the risk of reusing already compressed or no longer suitable gaskets. This product falls into the category Engine parts and oils and is designed for professional use in workshops or for experienced maintenance technicians.

Spare part features and details

The product is uniquely identified by the Mercury-MerCruiser code 26-816575A2 (also listed as MC26-816575A2). Correct identification of the code is essential to avoid procurement errors and to ensure correspondence with the spare parts breakdown of the engine or group being serviced.

Key points

• Type: Seal kit / gasket kit (Sealkit-OBM).
• Product code: MC26-816575A2 (Mercury-MerCruiser 26-816575A2).
• Brand: Mercury.

Original spare part (OEM) vs aftermarket

This kit is described as genuine Mercury Marine factory OEM part, therefore an official supply component. Practically speaking, choosing an OEM spare part is useful when you want to:

• maintain the consistency with the manufacturer's specifications;
• reduce uncertainties related to unofficial variants;
• manage interventions in which the code traceability it is an operational requirement (workshop, refit, scheduled maintenance).

Typical applications

A seal kit it is normally used when working on assemblies that require the replacement of seals during reassembly. In the nautical field, this can involve various ordinary or extraordinary maintenance operations on engines and associated components.

When a gasket kit can be useful

• Disassembly and reassembly of components that include sealing elements.
• Overhaul of assemblies where it is good practice to replace gaskets during the intervention.
• Restoration after inspections or maintenance that require opening a crankcase or housing.
• Preventive maintenance on the occasion of scheduled work, when it is preferable to already have the necessary seals available.

Compatibility: how to check it correctly

To avoid incorrect purchases, it is recommended to:

• compare the code 26-816575A2 with the Mercury/MerCruiser spare parts exploded view of your engine or assembly;
• check for any code revisions or replacements (supersession) indicated by the manufacturer;
• in case of doubt, provide the serial number of the engine or lower unit and the code present on the component to be replaced (if available).

Why choose this Sealkit-OBM

• Clear identification: the code MC26-816575A2/26-816575A2 facilitates alignment with the technical documentation.
• “Kit” approach: practical solution for interventions where it is appropriate to replace seals during reassembly.
• OEM spare part: recommended for those who prefer original Mercury Marine components over aftermarket solutions.
• Suitable for professional contexts: useful in the workshop and onboard maintenance, where proper sealing and seal management are central aspects.

Usage and important notes

A gasket kit requires careful installation in accordance with the manufacturer's procedures. Seals function correctly only if mounted on clean, intact surfaces with proper fittings. Below are some general guidelines (not a substitute for the technical manual):

General installation guidelines

• Preliminary check: check that the kit code matches the one required by the spare parts exploded view.
• Surface cleaning: remove residues of old gaskets and contaminants before assembly.
• Inspection of seals: check that the sealing seats do not have scratches or obvious defects.
• Ordered assembly: arrange the components on the bench and follow the reassembly sequence provided by the manual.
• Final check: after reassembly, perform a visual and functional check according to workshop procedures.

Notes on supply and identification

• Supplier code: MC26-816575A2.
• Supplier: D’ARPA MOTORI SRL.
• Internal SKU: DARP000048.

For technical requests or support in verifying compatibility, it is useful to have the complete code at hand and, if possible, the identification data of the engine/group being worked on.
