      Yamaha OEM Engine Parts Finder

      Shop Yamaha Outboard Parts

      Wholesale Marine stocks thousands of OEM and aftermarket marine engine parts, including Yamaha outboard parts for routine maintenance, repairs, and complete engine service. Whether you are replacing a worn component, servicing an engine system, or preparing your outboard for the boating season, our selection includes genuine Yamaha parts and trusted aftermarket alternatives.

      Shop Yamaha replacement parts for cooling, fuel, ignition, electrical, lubrication, control, trim, and propulsion systems.

      Browse our selection to find parts for Yamaha outboard maintenance, repair, and engine service.

      Find the Right Parts for Your Yamaha Outboard

      Yamaha outboard parts can vary by engine model, horsepower, production range, model year, and serial number. Two outboards with the same horsepower rating may not always use the same components, so confirm your engine information before ordering whenever possible.

      Use our Yamaha Engine Parts Finder to narrow the available parts by engine model and part type. This makes it easier to locate maintenance items, repair components, and replacement parts for your specific Yamaha outboard.

      When confirming fitment, have the following information available:

      • Engine model number
      • Primary identification number or serial number
      • Horsepower
      • Model year or production information
      • Existing OEM part number, when available

      Use Yamaha Engine Breakdowns and Boat Schematics

      A Yamaha engine breakdown provides an exploded view of the systems and assemblies within the outboard. These diagrams can help you determine where a component is installed, identify surrounding hardware, and see whether related seals, gaskets, fasteners, or service parts may also be required.

      Our Yamaha boat schematics organize components by engine model and assembly, making it easier to locate parts for cooling, fuel, ignition, electrical, powerhead, lower unit, control, and trim systems. Select the correct Yamaha outboard model and assembly before reviewing the available OEM and aftermarket replacement parts.

      The number displayed beside a component in an engine breakdown may be a diagram reference number rather than the orderable manufacturer part number. Match the reference number to the accompanying parts list to confirm the current part number and determine whether the original number has been superseded.

      OEM and Aftermarket Yamaha Outboard Parts

      Wholesale Marine offers both genuine OEM Yamaha components and aftermarket replacement parts. OEM parts are manufactured or approved for the original Yamaha application. Aftermarket parts are produced by other manufacturers and may provide additional availability, value, or service options while replacing the same type of engine component.

      Always review the listed fitment information before selecting a replacement. When an original Yamaha part number has been discontinued or superseded, the current replacement may use a different part number while serving the same application.

      Common Yamaha Maintenance and Repair Parts

      Regular maintenance helps protect your Yamaha outboard from corrosion, overheating, fuel-system problems, and premature component wear. The parts required will depend on the engine model, operating conditions, and recommended service interval.

      Common Yamaha outboard maintenance and repair parts include:

      • Anodes: Help protect submerged metal components from galvanic corrosion.
      • Fuel-system parts: Include fuel filters, pumps, lines, carburetor components, and fuel-injection parts.
      • Cooling-system parts: Include water pumps, impellers, thermostats, housings, and related seals.
      • Ignition parts: Include spark plugs, ignition coils, stators, switches, and other starting and ignition components.
      • Electrical parts: Include starter motors, relays, sensors, switches, and charging-system components.
      • Oil and filters: Support proper lubrication and routine service for Yamaha four-stroke outboards.
      • Propellers and propeller hardware: Transfer engine power to the water and help determine acceleration, engine speed, and overall boat performance.
      • Trim-system parts: Include trim motors, relays, seals, and related components used to adjust the outboard’s running angle.

      Maintain Yamaha Two-Stroke and Four-Stroke Outboards

      Yamaha two-stroke and four-stroke outboards have different maintenance requirements, so always follow the service schedule and specifications for your exact engine model. Routine service may include replacing engine oil and filters, gearcase lubricant, fuel filters, spark plugs, water pump components, anodes, and other wear items.

      Inspect cooling-system components regularly and flush the outboard with fresh water as recommended, especially after use in saltwater or silty conditions. Fuel lines, filters, electrical connections, propeller hardware, and corrosion-protection components should also be checked periodically for wear or damage.

      Refer to your Yamaha owner’s or service manual for the correct maintenance intervals, fluids, capacities, replacement procedures, and torque specifications for your engine.

      Yamaha Outboard Parts FAQs

      Does Wholesale Marine carry OEM and aftermarket Yamaha outboard parts?

      Yes. Wholesale Marine stocks thousands of OEM and aftermarket marine engine parts, including genuine Yamaha components and trusted aftermarket replacements. Available parts cover routine maintenance, cooling, fuel, ignition, electrical, lubrication, powerhead, lower unit, control, and trim systems.

      How do I find the correct Yamaha part for my outboard?

      Start with your engine model number, serial number, and horsepower, then use the Wholesale Marine Yamaha Engine Parts Finder to narrow the available parts by engine and part type. Because components can vary by production range and configuration, do not rely on horsepower alone when confirming fitment.

      How do I use a Yamaha engine breakdown or boat schematic?

      Select your Yamaha outboard model, then choose the system or assembly you need to repair. The engine breakdown will display an exploded diagram with numbered components. Match the diagram reference number to the accompanying parts list to locate the current OEM or aftermarket replacement part.

      Why do I need my Yamaha outboard model and serial number?

      The model and serial number help identify the outboard’s production range and exact configuration. Yamaha may use different components within the same horsepower or engine family, so this information can help distinguish between parts that appear similar but fit different applications.

      What is the difference between OEM and aftermarket Yamaha parts?

      OEM parts are manufactured or approved for the original Yamaha application. Aftermarket parts are produced by another manufacturer as replacement options and may provide different pricing, availability, or material choices. The best option depends on the repair, application, and listed fitment requirements.

      What does it mean when a Yamaha part number has been superseded?

      A superseded part number means the original Yamaha number has been replaced by a newer orderable number. The replacement may include a design, material, packaging, or manufacturing update. Always verify that the newer number is listed as the correct replacement for your outboard application.

      Can Wholesale Marine help me identify a Yamaha outboard part?

      Yes. Our marine parts specialists can help review your model number, serial number, horsepower, existing part number, and available parts information. We can also help you navigate available engine breakdowns and boat schematics. Call 877-388-2628 Monday through Friday from 8:30 AM to 4:30 PM with as much engine information as possible.
