Shop Yamaha Outboard Engine Parts
Yamaha Outboard Parts
Yamaha outboard parts support critical engine systems including lubrication, fuel delivery, cooling, ignition, electrical, steering, trim and tilt, and propulsion. Because compatibility can vary by engine family, horsepower, model year, and production range, use your Yamaha engine model and identification information when selecting replacement parts.
Yamaha Four-Stroke Engine Parts

Yamaha Portable Outboard Parts
Maintain smaller Yamaha engines with Yamaha portable outboard parts for dinghies, tenders, inflatables, fishing boats, jon boats, and other compact vessels. Portable engines still require regular maintenance of fuel, cooling, ignition, lubrication, and lower unit systems.
Yamaha Maintenance Parts
Yamaha Oil Filters
Yamaha oil filters help remove contaminants from engine oil as it circulates through compatible four-stroke outboards. Replace the filter according to the maintenance schedule for your specific engine and confirm fitment using the Yamaha model and engine information.
Yamaha Fuel Filters
Protect your outboard's fuel system with compatible Yamaha fuel filters. Depending on the boat and engine, the system may include engine-mounted filters, inline filters, and water-separating fuel filters designed to help reduce contaminants and moisture before they reach the engine.
Yamaha Spark Plugs
Maintain reliable ignition with the correct spark plugs for your Yamaha outboard. Plug type and gap can vary between engine families and horsepower ranges, so always use the specifications recommended for your specific Yamaha engine.
Yamaha Maintenance Kits
Simplify scheduled service with a compatible Yamaha outboard maintenance kit. Depending on the engine and kit, contents may include filters, spark plugs, anodes, thermostats, water pump parts, gaskets, seals, and other frequently replaced maintenance components.
Yamaha Water Pump & Cooling System Parts
Yamaha Water Pump Kits
A Yamaha water pump kit can provide the components needed to service a compatible outboard cooling system. Kits may include an impeller, wear plate, housing, gaskets, seals, and related hardware depending on the engine and selected kit.
Yamaha Water Pump Impellers
The Yamaha outboard water pump impeller helps circulate cooling water through the engine. Impellers wear over time and should be inspected or replaced according to Yamaha maintenance recommendations and operating conditions.
Yamaha Thermostats
Yamaha thermostats help regulate engine temperature by controlling coolant flow through the outboard cooling system. Replace worn or malfunctioning thermostats with components specified for your exact Yamaha engine.
Yamaha Fuel System Parts
Yamaha Fuel Pumps & Components
Maintain dependable fuel delivery with compatible Yamaha fuel-system parts. Depending on the engine, replacement components can include fuel pumps, filters, hoses, connectors, fittings, seals, and other parts used throughout the fuel system.
Yamaha Fuel Lines & Connectors
Inspect Yamaha fuel lines, primer bulbs, fittings, and connectors for cracks, leaks, deterioration, or loose connections. Replace damaged components with products designed for your specific engine and marine fuel system.
Yamaha Water-Separating Fuel Filters
Water-separating fuel filters can help protect compatible Yamaha engines by filtering contaminants and separating water from the fuel supply before it reaches sensitive engine components.
Yamaha Electrical & Ignition Parts
Yamaha Ignition Parts
Shop compatible Yamaha ignition parts for engine starting and operation. Depending on the outboard, ignition-system components may include spark plugs, ignition coils, sensors, switches, wiring, and other electrical parts.
Yamaha Sensors & Switches
Yamaha sensors and switches support engine monitoring, control systems, alarms, trim functions, and other onboard operations. Because modern Yamaha outboards may use advanced electronic engine management, replacement sensors should be matched carefully to the specific engine.
Yamaha Relays & Solenoids
Find compatible Yamaha relays and solenoids used in starting, power trim and tilt, and other engine electrical systems. Proper troubleshooting can help identify the source of an electrical issue before parts are replaced.
Yamaha Trim & Tilt Parts
Maintain convenient engine positioning with compatible Yamaha trim and tilt parts. Depending on your outboard, available components may include trim switches, relays, seals, hydraulic parts, motors, and related hardware.
Yamaha Trim Switches
Yamaha trim switches allow compatible power trim and tilt systems to be controlled from the engine or helm. Replace worn or damaged switches with components designed for your particular engine and control system.
Yamaha Anodes & Corrosion Protection
Yamaha Outboard Anodes
Yamaha sacrificial anodes help protect compatible underwater engine components from galvanic corrosion. Inspect anodes regularly and replace them when sufficiently deteriorated. The appropriate anode material can depend on whether the boat operates in freshwater, brackish water, or saltwater.
Yamaha Trim Tab Anodes
Some Yamaha outboards use trim tab anodes or other strategically positioned sacrificial anodes. Choose replacement anodes that match your specific engine and operating environment.
Yamaha Propeller Parts & Hardware
Yamaha Propeller Hardware
Complete compatible propeller installations with Yamaha propeller hardware, including nuts, washers, spacers, thrust washers, cotter pins, and related components. Follow manufacturer installation and torque specifications when servicing a propeller.
Yamaha Propeller Hubs
Connect compatible propellers to your outboard with the correct Yamaha propeller hub components. Hub requirements vary based on engine, gearcase, and propeller, so verify compatibility before installation.
Yamaha Gaskets, Seals & Engine Hardware
Complete maintenance and repair projects with compatible Yamaha gaskets, O-rings, seals, drain plug gaskets, and engine hardware. Small sealing components are often replaced whenever related parts are removed for service.
Yamaha Lower Unit Seals & Gaskets
Proper Yamaha lower unit seals help keep gear lubricant inside the gearcase and water outside. Inspect drain plug gaskets, shaft seals, and other sealing components during lower-unit maintenance and replace them as recommended.
Yamaha Lower Unit & Gearcase Parts
Yamaha Lower Unit Components
The lower unit transfers engine power to the propeller through shafts, gears, bearings, and related components. Shop compatible Yamaha lower unit parts and service items based on your engine and gearcase configuration.
Yamaha Drain Plugs & Gearcase Hardware
Maintain the lower unit with compatible Yamaha drain plugs, gaskets, seals, and gearcase hardware. Inspect these components whenever changing lower unit gear lube or performing related service.
How to Find the Right Yamaha Engine Parts
Use Your Yamaha Engine Model
Start by identifying your exact Yamaha outboard model. Engines with similar horsepower can use different filters, spark plugs, water pumps, thermostats, electrical parts, and other components depending on engine family and production year.
Check Your Yamaha Engine Identification Information
Your engine identification information can help narrow down compatible replacement parts. Use the model designation, serial information, horsepower, and other engine details when selecting Yamaha maintenance and repair components.
Match the Yamaha Part Number
If you're replacing an existing component, identify the Yamaha part number whenever possible. Matching or cross-referencing the original part number can help distinguish between components that may look similar but are designed for different engines.
Don't Shop by Horsepower Alone
Two Yamaha outboards with the same horsepower rating may use different filters, spark plugs, water pump components, thermostats, gaskets, sensors, and electrical parts. Always verify engine-specific compatibility rather than choosing a part based only on horsepower.
Frequently Asked Questions About Yamaha Engine Parts
Yamaha Engine Parts FAQ
Start with your Yamaha engine's model, horsepower, and identification information. Use this information along with the original Yamaha part number, when available, to verify that a replacement component is compatible with your engine.
