Precision-Wound Replacement Stator for Mercury Outboards.
This CDI Electronics replacement stator is engineered as a direct fit for Mercury outboard engines, replacing OEM part number 1748778K1. The stator is the heart of your outboard's ignition and charging system — it generates the AC current that powers the ignition coils and charges the battery. When a stator fails, the engine may run rough, lose spark on one or more cylinders, or refuse to start entirely.
CDI Electronics is a leading manufacturer of marine ignition components, with a reputation for precision winding and rigorous quality control. For complete application fitment information, refer to the CDI Electronics application catalog using part number 667-1748778K1.

Parts Desk Insights
A stator is one of the more involved outboard repairs — it requires flywheel removal and careful reassembly — so it's worth confirming the diagnosis before ordering. Common symptoms of a failing stator include intermittent spark loss, misfiring at higher RPM, or a dead battery that won't hold a charge despite a good alternator. A marine technician with a multimeter can test stator output in minutes and confirm whether this is the right part before you commit.
If you're also seeing ignition coil or spark plug issues alongside stator symptoms, check the Mercury OEM Ignition Coil and Quicksilver NGK Iridium Spark Plug Set while you have the engine apart.
