Installation Guide

1. Disconnect the battery and relieve fuel system pressure by removing the fuel line from the engine. Allow any residual fuel to drain into an approved container.
2. Remove the engine cowling to access the fuel pump mounting area on the engine block.
3. Disconnect the fuel inlet and outlet lines from the old fuel pump, noting their orientation for reassembly.
4. Unbolt the old fuel pump from the engine block and carefully remove it along with the old gasket.
5. Clean the mounting surface on the engine block thoroughly to ensure a proper seal with the new gasket.
6. Position the new gasket onto the engine block mounting surface, aligning all bolt holes.
7. Install the new fuel pump onto the gasket, ensuring the pump diaphragm actuator aligns with the engine's cam or drive mechanism.
8. Hand-tighten the mounting bolts, then torque them to manufacturer specifications in a cross pattern to ensure even seating.
9. Reconnect the fuel inlet and outlet lines to the new pump, using the cable ties provided to secure hoses and prevent chafing.
10. Repeat steps 3–9 for the second fuel pump if your engine configuration requires dual pumps.
11. Reinstall the engine cowling and reconnect the battery.
12. Prime the fuel system by turning the ignition to the ON position several times, then start the engine and inspect all connections for leaks.

Troubleshooting & FAQ

Q: How do I confirm this fuel pump fits my Yamaha outboard?
A: Cross-reference your engine's model, horsepower, and year with the compatibility table above. You can also verify the OEM part number (6E5-24410-00-00) stamped on your existing pump or consult your engine's parts diagram using the Yamaha catalog link provided.

Q: Why does this kit include two fuel pumps?
A: Yamaha V4 and V6 2-stroke outboards in the 115–300 HP range typically use dual fuel pumps to supply adequate fuel volume at higher RPMs. This package contains both pumps needed for a complete replacement.

Q: What are the signs my fuel pump needs replacement?
A: Common symptoms include hard starting, engine stalling or hesitation under load, reduced top speed, poor acceleration, or visible fuel leaks around the pump body. A failing diaphragm may also cause fuel to mix with crankcase oil.

Q: How often should I replace the fuel pump?
A: Fuel pumps typically last several years depending on usage and fuel quality. Replace immediately if you notice performance issues or leaks. Inspect pumps annually and replace diaphragms every 3–5 years as preventive maintenance on high-use engines.

Q: Can I use this pump with ethanol-blended fuel (E10)?
A: Yes, this fuel pump is designed to handle gasoline and ethanol-blend fuels (up to E10) commonly used in marine applications. Always use fresh fuel and add a stabilizer if storing your engine for extended periods.
