Built for outboard ignition service, this stator supplies the charging voltage used by the ignition system while helping maintain consistent spark energy through the RPM range. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Stator Design

• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
• Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.
• Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
• Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.

Ignition System Benefits

• Provides a dependable electrical source for the ignition system under real-world boating conditions.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Helps restore ignition charge voltage for strong, repeatable spark output.
• Designed to maintain stable voltage as engine load and RPM change.

Common Symptoms of Stator Failure

• Engine misfire under load
• Hard starting
• Charging output problems where the stator also supports charging circuits
• Poor acceleration caused by weak ignition energy
• Spark loss after warm-up

Because stator failure can mimic other ignition problems, testing the trigger, coils, switch box or power pack, and related grounds is recommended.
