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 Johnson/Evinrude applications where ignition stability depends on clean stator output.

Design & Materials

  • Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
  • Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
  • Precision-wound copper coils are used to promote efficient voltage generation and stable output.
  • Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.

Performance Features

  • Supports smooth acceleration by helping the ignition system maintain consistent energy.
  • Engineered to meet OEM-style electrical output characteristics.
  • Helps correct intermittent spark loss caused by heat-sensitive stator windings.
  • Helps restore ignition charge voltage for strong, repeatable spark output.

Common Symptoms of Stator Failure

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

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