This marine stator assembly is engineered to generate the electrical energy needed for dependable CDI ignition performance across changing engine speeds. The design priorities are especially important on Johnson/Evinrude applications where ignition stability depends on clean stator output.

Stator Design

• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
• Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.
• Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.
• Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.

Ignition System Benefits

• Supports smooth acceleration by helping the ignition system maintain consistent energy.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Designed to maintain stable voltage as engine load and RPM change.
• Helps restore ignition charge voltage for strong, repeatable spark output.

Problems a Weak Stator Can Cause

• Hard starting
• Engine misfire under load
• Weak or intermittent spark
• Unstable ignition output
• Charging output problems where the stator also supports charging circuits

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