This outboard stator assembly is built to maintain dependable ignition energy as engine speed, heat, vibration, and load conditions change. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Materials & Build Quality

• 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.
• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
• Precision-wound copper coils are used to promote efficient voltage generation and stable output.

Key Functional Details

• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Helps restore ignition charge voltage for strong, repeatable spark output.
• Designed for use in wet, hot, and vibration-heavy marine engine compartments.
• Helps reduce high-RPM breakup caused by weak or unstable stator output.

Failure Symptoms to Check

• Charging output problems where the stator also supports charging circuits
• High-rpm breakup
• Spark loss after warm-up
• Poor acceleration caused by weak ignition energy
• Weak or intermittent spark

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