The stator is the stationary winding inside the flywheel that generates the electrical current used to charge the battery and power the ignition system while the engine runs. As the flywheel magnets rotate around the stator windings, alternating current is induced and fed to the rectifier or regulator, which converts it into usable DC power for the boat's electrical system.\u003c\/p\u003e\u003cp\u003eCDI Electronics designs and builds ignition and charging components for the marine and motorsport industry, focusing on consistent output and long service life in the vibration, heat, and moisture conditions typical of an outboard powerhead. A worn or failing stator is a common cause of weak battery charging, erratic tachometer readings, or a no-spark condition, so replacing it with a properly rated unit restores reliable charging output.\u003c\/p\u003e\u003cp\u003eThis stator is sized for Mercury 4 and 6 cylinder outboard powerheads and is supplied under part number 18-99237.
