CDI Stator for Mercury Outboards
This CDI stator replaces Mercury outboard part 174-6617K1 and supplies reliable ignition power to 2-cylinder 6–40 HP engines.
Overview
The CDI stator for Mercury outboards delivers consistent spark energy to keep your marine engine running smoothly. Designed as a direct electrical replacement for worn or failed stators, this component restores charging and ignition output on a range of mid-sized outboards. It fits popular 2-cylinder Mercury models from 6 to 40 horsepower, making it a practical pick for boat owners and marine technicians alike.

Good To Know
Q: How can I tell if the stator is the cause of my ignition problem? A: Test the stator with a multimeter for proper resistance and AC output while cranking; a reading far from factory spec usually means the CDI stator for Mercury outboards needs replacement.
Q: Does this stator also charge the battery? A: Yes, it includes a charge coil that sends power to the rectifier/regulator, so a faulty stator often leads to both weak spark and a discharged battery on the water.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
