Troubleshooting & FAQ
How do I confirm that this injector fits my engine?
Confirm that your engine is a MerCruiser 6.2L MPI or 8.2L MPI application from 1999 onward and compare the original injector with the primary reference 861260T. Verify the exact model, year, serial number, connector, and physical design before ordering.
Is this an OEM injector?
No. This is a 100% new aftermarket replacement injector intended for the specified MerCruiser MPI applications.
Is this sold as a set?
No. This listing is for one individual injector. If your engine requires multiple injectors, order the quantity needed for the repair.
Is the Sierra 18-7692 number the injector number?
No. 18-7692 identifies an injector seal kit in the Sierra catalog. It is not the individual fuel injector supplied with this listing.
What are common symptoms of a faulty fuel injector?
Possible symptoms include rough idle, misfire, hard starting, poor acceleration, increased fuel consumption, fuel odor, or an engine fault related to fuel delivery. Diagnosis should be performed using the engine service procedure and appropriate testing equipment.
Should I replace the injector seals during installation?
Inspect all seals during removal and replace damaged, hardened, or leaking seals as required by the service manual. Do not assume that a separate seal kit reference is included with this individual injector.
