What’s in the Box
- 1 × aftermarket fuel pump assembly
The related Sierra catalog identifies a separate fuel-pump kit, 18-7788, for diaphragm and gasket components used with this application. That overhaul kit is not included unless it is specifically stated in the order contents or shown as a separate product option.
Installation Notes
- Safety first: Disconnect the battery, allow the engine to cool, relieve fuel-system pressure where applicable, and work in a well-ventilated area away from ignition sources.
- Verify the replacement: Compare the new pump with the original unit, including mounting pattern, port orientation, fuel-line connections, and the complete OEM reference.
- Remove the old pump: Label the inlet and outlet hoses before removal. Use a suitable container or absorbent material to catch spilled fuel.
- Prepare the mounting surface: Remove old gasket material and contamination without damaging the engine mounting surface.
- Install the pump: Fit the correct gasket or sealing arrangement required for the specific engine. Tighten fasteners according to the engine manufacturer’s service specifications; do not guess torque values.
- Reconnect the fuel lines: Return the lines to their original locations and secure them with suitable clamps. Inspect hoses for cracking, hardening, or damage.
- Test for leaks: Prime the system as required, inspect all connections carefully, and stop immediately if fuel leakage is present. Do not operate the engine until the system is leak-free.
Troubleshooting & FAQ
How do I confirm fitment?
Compare the complete Yamaha engine model, horsepower, stroke, model year, and original fuel-pump number with the compatibility information above. The broad application is selected Yamaha 2-stroke outboards from 115 HP through 300 HP, generally covering 1984–2004.
What are common symptoms of a failing mechanical fuel pump?
Possible symptoms include hard starting, stalling, hesitation, loss of power, surging, or fuel leakage. These symptoms can also result from restricted fuel lines, clogged filters, carburetor problems, or ignition faults, so diagnose the complete fuel system before replacing the pump.
Is this a complete pump or an overhaul kit?
This listing is for a fuel pump assembly. A separate diaphragm-and-gasket overhaul kit may be required for rebuilding the pump and is not included unless explicitly listed in the package contents.
Does this product fit every Yamaha 115–300 HP 2-stroke engine?
No. The horsepower range alone does not confirm fitment. Yamaha used different fuel-pump references across years and model variants. Verify the complete model and original part number before ordering.
Is this an OEM Yamaha part?
No. This is an aftermarket replacement. The Yamaha numbers shown are OEM reference numbers used for identification and compatibility, not a claim that the product is manufactured by Yamaha.
Are the related gasket and diaphragm numbers included?
No. Related internal component numbers describe service or overhaul parts and should not be interpreted as included package contents. Check the separate kit listing if a rebuild kit is needed.
Safety & Important Information
- Confirm the exact engine model, year, horsepower, stroke, and original fuel-pump number before purchase.
- Do not rely on horsepower alone when confirming fitment.
- Inspect the pump, fuel lines, clamps, and connections for leaks before operating the engine.
- This is an aftermarket replacement, not a Yamaha OEM component.
- Professional installation is recommended when the correct mounting or fuel-system procedure is uncertain.
