  2. Record the engine serial number exactly as shown.
  3. Record the sterndrive model or generation and drive serial number where applicable.

MerCruiser Parts FAQs

What information do I need to find the correct MerCruiser part?

Start with the complete engine or drive designation and the relevant serial number. If the part belongs to the sterndrive or transom assembly, record those identification details as well. Similar engine capacities and drive names can cover different generations and component arrangements.

Are all products on this page genuine MerCruiser parts?

No. TMP Global sells listed replacement products that can include compatible aftermarket parts. Each product page identifies the offered brand and available OEM cross-references. Treat a product as genuine MerCruiser only when the listing states this explicitly.

Can I select a part using its MerCruiser OEM reference?

An OEM reference is a useful identification and cross-reference tool, but it should be checked alongside the engine or drive model, serial range and product fitment information before ordering.

How do the MerCruiser exploded parts diagrams work?

Choose the diagram for the correct engine or drive family and assembly, locate the numbered component, then use the corresponding parts-schedule row to view the listed reference and any available replacement product. Check the stated application limits before ordering.

What should I do if my MerCruiser engine or drive is not listed?

Use the Parts Finder or contact TMP Global with the complete engine, drive and transom details, the relevant serial numbers, any OEM reference and clear photographs of the identification labels and existing component.
