Product Details

This replacement stator is designed to support stable ignition output by converting flywheel rotation into controlled electrical energy for the ignition circuit. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Construction Details

  • Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.
  • High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
  • Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
  • Precision-wound copper coils are used to promote efficient voltage generation and stable output.

Ignition System Benefits

  • Helps restore ignition charge voltage for strong, repeatable spark output.
  • Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
  • Designed to maintain stable voltage as engine load and RPM change.
  • Supports dependable starting by delivering the voltage needed by the ignition module.

Common Symptoms of Stator Failure

  • Weak or intermittent spark
  • Hard starting
  • No-start conditions
  • High-rpm breakup
  • Poor acceleration caused by weak ignition energy

Always compare resistance and peak-voltage readings to the correct service specifications when diagnosing a suspected stator failure.
