CDI Electronics 174-2075K2 Stator - Mercury Mariner 2/3/4 Cyl 9 Amp, 30-125 HP (1995-2007)

The CDI Electronics 174-2075K2 is a replacement stator for Mercury and Mariner outboard engines, supplying the electrical current that charges the battery and powers the ignition system as the flywheel spins past its windings. A failing stator is a common cause of an outboard that will not start, stalls intermittently, misfires, or stops charging the battery, and this 9 Amp stator is built to restore that output on the applicable 2, 3, and 4 cylinder Mercury/Mariner powerheads.

CDI builds this stator with tighter windings and no nylon overcoating, a design intended to reduce the chances of overheating compared to less carefully wound units. The electrical components are made from corrosion-resistant parts and the assembly is insulated with a high-temperature compound, both aimed at extending service life in a marine environment. It is designed as a direct install onto the engines listed below, using the factory mounting points.
