Product Details

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

Materials & Build Quality

  • Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
  • Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
  • Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.
  • Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.

Performance Features

  • Helps restore ignition charge voltage for strong, repeatable spark output.
  • Helps correct intermittent spark loss caused by heat-sensitive stator windings.
  • Designed for use in wet, hot, and vibration-heavy marine engine compartments.
  • Provides a dependable electrical source for the ignition system under real-world boating conditions.

Common Symptoms of Stator Failure

  • Engine misfire under load
  • Unstable ignition output
  • No-start conditions
  • Spark loss after warm-up
  • High-rpm breakup

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