Package Contents

Your purchase includes the following components for complete installation:

• 1 × Fuel Pump Assembly
• 1 × O-ring Seal
• 4 × Mounting Clips

Installation Guide

1. Disconnect the battery and relieve fuel system pressure by removing the fuel line from the engine. Ensure the work area is well-ventilated.
2. Locate the existing fuel pump mounted on the side of the engine block. Note the orientation of fuel lines and electrical connections before removal.
3. Disconnect the fuel inlet and outlet hoses from the old pump. Have a rag ready to catch any residual fuel.
4. Remove the mounting clips or bolts securing the pump to the engine. Carefully pull the old pump away from the mounting surface.
5. Clean the mounting surface on the engine block, removing any old gasket material or debris. Ensure the surface is dry before proceeding.
6. Install the new O-ring onto the fuel pump body, ensuring it is seated properly in the groove. Do not use old seals.
7. Position the new fuel pump onto the engine block, aligning it with the mounting holes. Ensure the drive shaft engages correctly with the pump mechanism.
8. Secure the pump with the four mounting clips provided in the package. Tighten evenly to avoid distorting the pump body.
9. Reconnect the fuel inlet and outlet hoses to the corresponding ports on the new pump. Ensure hose clamps are tight and properly positioned.
10. Reconnect the battery and prime the fuel system by squeezing the primer bulb until firm. Check for fuel leaks around all connections.
11. Start the engine and allow it to idle for several minutes. Monitor fuel flow and listen for unusual noises from the pump.
12. Perform a final inspection of all connections and test the engine under normal operating conditions to confirm proper fuel delivery.

Troubleshooting & FAQ

Q: How do I confirm this fuel pump fits my specific Yamaha outboard?
A: Check theCompatibleEngine Models table above for your engine's model number and year range. You can also verify fitment by comparing the OEM part number (6AH-24410-00) on your current pump or by using the Yamaha serial number guide and parts diagrams linked in this listing.

Q: What are the symptoms of a failing fuel pump on these Yamaha engines?
A: Common signs include difficulty starting, rough idling, loss of power at higher RPMs, engine sputtering or stalling under load, and inconsistent fuel delivery. If your primer bulb won't stay firm or collapses during operation, the fuel pump may be worn or damaged.

Q: How often should I replace the fuel pump on my Yamaha outboard?
A: Fuel pump lifespan varies based on usage and fuel quality, but inspection is recommended every 200–300 operating hours or annually. Replace immediately if you notice fuel leaks, cracked diaphragms, or performance issues. Using fresh fuel and replacing inline filters regularly can extend pump life.

Q: Is any special priming required after installing this fuel pump?
A: Yes, after installation, disconnect the fuel line at the engine and use the primer bulb to fill the new pump and lines with fuel until the bulb is firm. Reconnect the line, then crank the engine in short bursts to purge air from the system before starting normally.

Q: Does this pump include the pulse line fitting and all necessary hardware?
A: This package includes the fuel pump assembly, one O-ring seal, and four mounting clips. If your installation requires additional fittings or hoses, those should be sourced separately or reused from your existing pump if in good condition.

A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.
