Installation Guide

  1. Disconnect the battery and relieve fuel system pressure before beginning work. Ensure the engine is cool and in a well-ventilated area.
  2. Locate the original fuel pump on your Yamaha 25HP 4-stroke outboard. Note the routing of fuel lines and electrical connections.
  3. Disconnect fuel lines from the inlet and outlet ports. Use a rag to catch any residual fuel.
  4. Unplug electrical connectors if your pump has wiring for sensors or priming systems. Label connections for reassembly.
  5. Remove mounting bolts securing the pump to the engine block. Keep hardware organized for reuse.
  6. Remove the old fuel pump assembly carefully. Inspect the mounting surface and gasket area for debris or damage.
  7. Clean the mounting surface thoroughly. Replace any worn gaskets or O-rings as needed.
  8. Position the new fuel pump onto the mounting surface, aligning bolt holes and ensuring proper orientation.
  9. Install mounting bolts and tighten evenly to manufacturer torque specifications. Do not over-torque.
  10. Reconnect fuel lines to inlet and outlet ports, ensuring clamps are secure and properly seated.
  11. Reconnect electrical connectors if applicable, matching labeled connections from disassembly.
  12. Reconnect the battery, prime the fuel system, and check for leaks before starting the engine. Run the engine and monitor for proper fuel delivery.

Troubleshooting & FAQ

Q: How do I confirm this fuel pump fits my Yamaha 25HP engine?
A: Check that your engine is a 25HP 4-stroke model manufactured from 2006 to present. Verify your current fuel pump bears one of the OEM part numbers listed (6BL-14301-00-00, 6BL-14301-10-00, 6BL-14301-11-00, or 6BL-14301-12-00). You can also reference your engine's parts diagram using the links in the Compatible Engine Models section above.

Q: What are the signs that my fuel pump needs replacement?
A: Common symptoms include difficulty starting, engine stalling or sputtering under load, inconsistent idle, reduced top speed, or visible fuel leaks around the pump housing. If you experience any of these issues, inspect the fuel pump for cracks, worn diaphragms, or damaged seals.

Q: How often should I replace the fuel pump on my outboard?
A: Fuel pumps typically last several years under normal conditions, but replacement intervals depend on usage, fuel quality, and maintenance. Inspect the pump annually and replace it if you notice performance issues or visible wear. Always use fresh, clean fuel and replace fuel filters regularly to extend pump life.

Don’t waste your money. Your dog will be eating plastic…
Color: Pink
My dog ends up chewing the plastic ends which is destructible, so I took it away from her. She loved it though and the colors are cute. But eating plastic isn’t ever a good thing. I recommend sticking to actual bones or something else, not this.

This is not a safe indestructible toy
DO NOT BUY! My 22 lb doodle destroyed this within the hour. He had all the nubs of two of the rings completely chewed off and was chewing them like gum. He is only 9 months old.
