INJECTOR 95495M REC677-14343-68

Function and technical context

The 95495M fuel injector is an essential component of the fuel delivery system on Mercury and Yamaha 15C and W15 series engines. Its function is to atomize and spray the fuel directly into the combustion chamber, guaranteeing an optimal air-fuel mixture that enables efficient and controlled combustion. Integrated into the intake manifold or engine cylinder head, it works under regulated pressure to precisely dose the exact amount of fuel required by the engine in each operating cycle. A defective or partially clogged injector significantly reduces the available power, increases fuel consumption and causes serious instability during cold starts and idling.

When to replace this part?

Fuel injectors should be inspected each boating season and replaced if symptoms such as persistent difficulty starting, intermittent misfires, unstable idle, or abnormal engine vibrations occur. Progressive clogging caused by carbon deposits and fuel residues is the most frequent cause of failure in this component, being especially critical in moderate power engines such as those with 15 hp. Replacing the injector preventively when these symptoms appear avoids costly repairs and ensures the reliability of the propulsion system during navigation.
