Use Our OEM Parts Lookup »Shop Outboard Parts by Engine System
Outboard engines use several interconnected systems. Select your manufacturer above to browse the exact categories available for your engine, including the following common repair and maintenance areas.
Common Outboard Problems and Where to Start
- Engine overheating: inspect the water pump, impeller, thermostat, pressure-control components, cooling passages, and engine anodes.
- Hard starting or rough idle: check fuel delivery, carburetor or injector operation, spark plugs, ignition components, filters, and intake sealing.
- Weak spark or no spark: test ignition coils, stators, switch boxes or ignition modules, sensors, wiring, grounds, and related electrical components.
- Low compression or poor power: inspect pistons, rings, cylinder condition, head and powerhead gaskets, bearings, and other internal engine components.
- Milky gear lube: inspect prop shaft, driveshaft, shift shaft, bearing carrier, and other lower unit seals for water intrusion.
- Lower unit or gearcase noise: inspect bearings, gears, clutch components, shafts, and gear lube condition before continued operation.
- Trim or steering problems: inspect hydraulic fluid level, seals, hoses, trim motors, pumps, steering cylinders, and mechanical connections.

OEM and Aftermarket Outboard Parts
OEM parts are supplied by the original engine manufacturer and are designed for the specific engine application. Aftermarket parts are replacement components produced by independent marine parts manufacturers and may provide additional availability or value for many common repairs.
Pro Marine carries both genuine OEM parts and quality aftermarket replacement parts for many outboard maintenance, repair, and rebuild applications. Always confirm fitment using the engine model, serial number, horsepower, year range, or OEM part number when available.
Frequently Asked Questions
How do I find the correct parts for my outboard motor?
Start by identifying the engine manufacturer, horsepower, model number, serial number, and year. Select the manufacturer above to browse by engine system, or use the OEM parts lookup to locate the original part number from a factory diagram.
Can I search Pro Marine by OEM part number?
Yes. If you already have the OEM part number, enter it into the Pro Marine site search to locate available OEM and aftermarket replacement options. If you do not know the part number, use the OEM parts lookup first.
What information should I have before ordering an outboard part?
Have the engine manufacturer, horsepower, model number, serial number, and year whenever possible. An OEM part number from the original component or parts diagram is especially helpful because visually similar parts may fit different engine families.
What is the difference between OEM and aftermarket outboard parts?
OEM parts come from the original engine manufacturer. Aftermarket parts are replacement components manufactured by other marine parts companies for compatible applications. Pro Marine carries both OEM and aftermarket options across many common outboard engine systems.
Are aftermarket outboard motor parts reliable?
Quality aftermarket marine parts are commonly used for maintenance, professional repair, and engine rebuilding. The best option depends on the application, manufacturer, availability, and customer preference.
Do you carry parts for older outboard motors?
Yes. Pro Marine carries parts for many older Mercury, Mariner, Johnson, Evinrude, Chrysler, Force, Yamaha, Honda, Suzuki, Nissan, and Tohatsu outboards. Availability varies by engine family and component.
What outboard parts are commonly replaced during routine maintenance?
Common maintenance items include engine oil, oil filters, fuel filters, spark plugs, water pump impellers, complete water pump kits, thermostats, gear lube, drain plug seals, anodes, and manufacturer-specific service kit components.
Fitment Tip: Outboard parts can vary by model, serial range, horsepower, and production year. Confirm the OEM part number or engine identification information whenever possible before ordering.

Johnson / Evinrude Electric Fuel & Oil Pump
Johnson Evinrude 40-300HP Fuel & Oil Pump - 8403
The 8403 Electric Fuel & Oil Pump is a replacement fuel/oil delivery pump used across a very broad range of Johnson, Evinrude, OMC, and BRP outboards. Verified applications in the supplied catalog span numerous 1990-2002 model-year engines and cover many horsepower ranges from 40HP through 300HP.
This pump cross references a large family of original OMC / BRP fuel and oil pump numbers, including 0174933, 0435555, 5004558, 5007420, and 769076. Always verify the complete engine model number and original pump number before ordering.
The supplied fitment information states that this kit is used to replace 3-wire pumps on all motors except 2-cylinder 40HP and 50HP engines.
Additional parts may be required:
- Order harness 174710 on engines without "No Oil Warning" wiring.
- On 1984-1985 V6 cross-scavenged engines, bracket 331122 is also required.
Compatible Applications

Pro Marine Replacement Available
Pro Marine 8403P Electric Fuel & Oil Pump
Looking for a lower-cost replacement option? The Pro Marine 8403P is the Pro Marine branded version for these compatible Johnson / Evinrude fuel and oil pump applications.
It is a good alternative when replacing an older OMC / BRP pump that cross references one of the OEM numbers listed above.
What This Part is Used For
This pump is part of the engine's combined fuel and oil delivery system. On compatible Johnson and Evinrude two-stroke engines, the assembly supplies fuel to the engine while also working with the oil-injection system to provide lubrication.
A weak, leaking, or failed fuel/oil pump can contribute to hard starting, poor acceleration, fuel starvation, inconsistent engine operation, or oil-delivery concerns.
Because these engines use several different pump configurations and wiring arrangements, always compare the original pump, connector configuration, engine model number, and OEM part number before installation.
Common Reasons for Replacement
- Fuel leakage from the pump assembly
- Hard starting or extended cranking
- Fuel starvation at higher RPM
- Loss of engine power under load
- Old or damaged pump housing
- Replacement of an obsolete earlier 3-wire pump
- Fuel or oil delivery issues traced to the pump assembly
Important Installation Information
- Verify the complete engine model number before ordering
- Match the original pump to one of the OEM numbers listed above
- Check the electrical connector and warning-system wiring
- Harness 174710 may be needed if the engine lacks "No Oil Warning" wiring
- Bracket 331122 is required on applicable 1984-1985 V6 cross-scavenged engines
- The supplied catalog excludes 2-cylinder 40HP and 50HP engines from the 3-wire pump replacement note
FAQ
What engines does fuel/oil pump 8403 fit?
