Product Details

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 Mercury/Mariner applications where ignition stability depends on clean stator output.

Design & Materials

  • 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.
  • Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.
  • The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.

Performance Features

  • Supports dependable starting by delivering the voltage needed by the ignition module.
  • 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.
  • Designed for use in wet, hot, and vibration-heavy marine engine compartments.

Failure Symptoms to Check

  • Poor acceleration caused by weak ignition energy
  • High-rpm breakup
  • Weak or intermittent spark
  • Charging output problems where the stator also supports charging circuits
  • Engine misfire under load

For best results, stator output should be verified with the proper service-manual resistance and DVA voltage tests before installation.
