Mercury Outboard Parts & OEM Marine Parts

Shop OEM Mercury outboard parts and Mercury marine parts by engine model, horsepower, system, service interval, or OEM part number. Use Shop By Engine, category navigation, product fitment notes, and Mercury schematics to confirm the correct service or replacement component before ordering.

Mercury outboard motors rely on precise factory-matched parts to maintain performance, reliability, and long-term engine life. PartsVu carries OEM Mercury parts for routine maintenance, repairs, and common service intervals, including service kits, filters, oils, anodes, propellers, cooling components, ignition parts, fuel-system parts, rigging components, and lower-unit parts.

Find Mercury Parts by Model or Part Number

Use the Shop By Engine tool on this page to narrow Mercury parts by horsepower, model, and year. For more specific repairs, use the OEM number from the original component, a Mercury parts diagram, or service documentation and confirm any supersession and fitment information before ordering.

1. Identify your engine by model, horsepower, year, production information, or OEM part number.
2. Choose the most specific Mercury parts category for the system you are servicing.
3. Compare the product fitment information with your engine details.
4. Check whether an older OEM part number has been superseded by a current Mercury number.
5. Use Mercury schematics when you need to identify a specific component or part number.

Shop Mercury Outboard Parts by System

Use the most specific category for the part or maintenance job you need. This keeps broad Mercury parts shopping on this hub while dedicated collections cover individual systems and product families in more detail.

• Mercury 100- and 300-hour service kits – maintenance kits for routine service intervals. Verify the engine model, horsepower, production range, service interval, and kit contents.
• Mercury outboard oil change kits – oil, filters, and related supplies for compatible four-stroke Mercury outboards. Confirm engine model and oil requirements before ordering.
• Mercury filters and strainers – oil filters, fuel filters, and strainers for routine fuel and lubrication-system maintenance.
• Mercury lubes, oils, and additives – engine oil, gear lube, fuel additives, and corrosion-protection products.
• Mercury thermostats and cooling parts – thermostats, water-pump components, and related cooling-system parts. Confirm model, year or production range, component, and OEM part number.
• Mercury water pump repair kits – impellers, gaskets, plates, and other components used for water-pump service.
• Mercury fuel and oil system parts – fuel lines, pumps, fittings, filters, carburetor parts, and injection-related components. Verify the system location, connector or specification, engine model, and current OEM part number.
• Mercury rigging and throttle controls – steering, throttle, control, cable, harness, and rigging components. Confirm whether the application uses mechanical, DTS, or SmartCraft systems and verify connectors and part numbers.
• Mercury outboard gauges – gauges and compatible instrumentation for Mercury marine applications.
• Mercury outboard propellers – propellers, hubs, thrust washers, nuts, and related hardware. Match the engine and gearcase, diameter, pitch, hub system, rotation, and OEM number where applicable.
• Mercury lower-unit parts – gearcase, driveshaft, prop-shaft, transmission, seals, and related lower-unit components.
• Mercury anodes – sacrificial anodes designed to help protect compatible marine components from galvanic corrosion.

Why Choose OEM Mercury Outboard Parts?

OEM Mercury parts are designed to match Mercury factory specifications for fit, function, and engine compatibility. For routine maintenance and repairs, genuine Mercury replacement parts can make it easier to confirm the correct application by engine details and OEM part number.

OEM Mercury parts are commonly preferred because they are built for Mercury marine applications, designed around factory specifications, and easier to identify using current or superseded Mercury part numbers. Exact fitment is especially important when replacing cooling, fuel, ignition, electrical, rigging, or lower-unit components.

Aftermarket parts may be suitable for some applications, but the same fitment checks still apply. Do not assume that similar-looking Mercury components are interchangeable between engine families or production ranges.

How to Choose the Right Mercury Outboard Part

Start with your Mercury engine model, horsepower, year or production information, and OEM part number whenever possible. Parts can vary by engine family, horsepower, control system, and production range, so verify the application rather than relying on appearance alone.

Before ordering, confirm:

• Mercury engine model and horsepower
• Model year or applicable production range
• Two-stroke or four-stroke engine type where relevant
• OEM part number on the original component or diagram
• Whether the original number has been superseded
• The specific system or component being serviced
• Whether you need an individual component or a complete service kit
• Whether related seals, gaskets, washers, or hardware are required for the repair

For example, a Mercury water-pump repair should be matched to the correct repair kit, impeller, gasket, plate, or seal for the engine application. Routine service should likewise follow the maintenance requirements for the specific Mercury engine and service interval.

Common Mercury Parts by Maintenance Need

For 100-Hour Mercury Outboard Service

Common maintenance items can include engine oil, oil filters, fuel filters, gear lube, spark plugs, anodes, lubricants, and drain-plug gaskets. A preassembled Mercury service kit can simplify parts selection, but always confirm that the kit matches the engine model and applicable service interval.

For Cooling System Maintenance

Cooling-system service can involve water-pump repair kits, impellers, thermostats, gaskets, seals, poppet valves, and related hardware. Browse Mercury thermostats and cooling parts and verify the exact engine application before ordering.

For Fuel and Ignition Issues

Common fuel and ignition components include fuel filters, fuel lines, primer bulbs, pumps, carburetor or injection-system parts, spark plugs, ignition coils, and electrical connectors. Match the component to the engine system, model, and OEM part number whenever possible.

For Lower-Unit and Propeller Service

Lower-unit and propeller service can require gear lube, propellers, propeller hubs, thrust washers, prop nuts, cotter pins, prop shafts, seals, and related hardware. Verify gearcase compatibility as well as propeller diameter, pitch, hub system, and rotation when selecting a replacement propeller.

Mercury Parts, MerCruiser Parts, and Shared SKU Notes

Some Mercury Marine SKUs are used across more than one application, including select Mercury outboard and MerCruiser engine or drive applications. Because this overlap can occur, always match the exact OEM part number and listed application rather than assuming compatibility based on the Mercury Marine brand alone.

When a Mercury part number has been discontinued or superseded, use the current replacement number shown in the product or catalog information and recheck application details before ordering.
