Product Details

This replacement stator is designed for stable output and long service life in harsh outboard environments where heat, moisture, and vibration are constant concerns. The design priorities are especially important on Johnson/Evinrude applications where ignition stability depends on clean stator output.

Materials & Build Quality

  • Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.
  • 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.
  • Precision-wound copper coils are used to promote efficient voltage generation and stable output.

Performance Features

  • Helps correct intermittent spark loss caused by heat-sensitive stator windings.
  • Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
  • Supports smooth acceleration by helping the ignition system maintain consistent energy.
  • Designed for use in wet, hot, and vibration-heavy marine engine compartments.

Common Ignition Symptoms

  • Weak or intermittent spark
  • High-rpm breakup
  • No-start conditions
  • Poor acceleration caused by weak ignition energy
  • Spark loss after warm-up

A stator should be diagnosed as part of the complete ignition system so related components are not overlooked.
