Troubleshooting & FAQ
How do I know if this fuel injector fits my Honda outboard?
This listing is for a 100% new aftermarket injector for Honda Marine 4-stroke outboards in the BF115 through BF250 range. The available fitment records name BF135, BF150, BF225, and BF250, while catalog data also identifies BF140 and BF175 applications. Check your exact model designation, serial number, connector, and the original manufacturer part number 16450-ZY6-003 before ordering.
Is this an OEM Honda injector?
No. This is an aftermarket replacement component. Honda and the displayed part number are used only to identify the applicable manufacturer reference and fitment comparison.
Is the injector 100% new?
Yes. The company product record specifies that this injector is 100% new.
How many injectors are included?
One fuel injector assembly is included. This listing is for a single injector, not a four-piece set.
Are O-rings, filters, and grommets included?
Those additional installation components are not confirmed as included for this product. Inspect the original parts and check the engine service manual for the correct sealing components before installation.
What are common symptoms of a failing fuel injector?
Possible symptoms include hard starting, rough idle, misfiring, hesitation, poor acceleration, uneven running, or increased fuel consumption. Diagnose the fuel system and electrical circuit before replacing an injector.
Can I install this injector myself?
Injector replacement involves fuel pressure, electrical connections, sealing surfaces, and leak inspection. Follow the engine service manual exactly, or have the work completed by a qualified marine technician.
What should I do if my model appears in the horsepower range but the part looks different?
Do not install the part based on horsepower alone. Compare the original injector, connector, mounting arrangement, manufacturer part number, model variant, and serial-number requirements. If any critical detail differs, confirm compatibility before purchase.
