CDI Electronics Stator for Mercury 4/6 Cylinder Outboards, 10 Amp, Part 18-99237

This CDI Electronics stator is an ignition charging component built for Mercury 4 and 6 cylinder outboard engines, rated at 10 amp output. 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.

CDI 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.

This stator is sized for Mercury 4 and 6 cylinder outboard powerheads and is supplied under part number 18-99237. It measures 6 x 6 x 1.75 inches and weighs 1.6 pounds.

Frequently Asked Questions

What engines does the 18-99237 stator fit? Part number 18-99237 is built for Mercury 4 cylinder and 6 cylinder outboard engines.

What is the amperage rating of this stator? This stator is rated at 10 amp output, matching the charging capacity of the Mercury 4/6 cylinder outboard it is designed for.

How much does the 18-99237 stator weigh? It weighs 1.6 pounds.

What are the physical dimensions of this stator? The stator measures 6 x 6 x 1.75 inches.

What does a stator actually do on an outboard motor? It is the stationary winding inside the flywheel that generates alternating current as the flywheel magnets spin past it, and that current is then converted to DC to charge the battery and run the ignition system.

What symptoms indicate a failing stator? Weak or no battery charging, an erratic or dead tachometer, or an intermittent no-spark condition are common signs of a failing stator on Mercury 4/6 cylinder outboards, and replacing it with part 18-99237 restores proper charging output.

Who manufactures the 18-99237 stator? It is manufactured by CDI Electronics, a company focused on ignition and charging components for marine and motorsport engines.

Is this stator a new component or a rebuild? Part 18-99237 is a new CDI Electronics stator, not a rebuilt or reconditioned unit.

Does this stator include mounting hardware? The listing for part 18-99237 covers the stator itself; no additional mounting hardware is specified with it.

Can this stator be used on both 4 and 6 cylinder Mercury outboards? Yes, part 18-99237 is designed to fit both Mercury 4 cylinder and 6 cylinder outboard engines.

Why choose a CDI Electronics stator over a generic replacement? CDI Electronics specializes in marine ignition and charging components, and the 18-99237 stator is engineered specifically for the charging demands of Mercury 4/6 cylinder outboards rather than a generic universal fit.
