Product Details

This stator assembly is built to help the ignition system maintain clean spark delivery by supplying consistent electrical output as the flywheel rotates. The design priorities are especially important on Mercury/Mariner 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.
  • 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.
  • Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.

Operating Features

  • Helps reduce high-RPM breakup caused by weak or unstable stator output.
  • Helps restore ignition charge voltage for strong, repeatable spark output.
  • Designed to maintain stable voltage as engine load and RPM change.
  • Designed for use in wet, hot, and vibration-heavy marine engine compartments.

Common Symptoms of Stator Failure

  • Hard starting
  • Random cylinder drop-out
  • Poor acceleration caused by weak ignition energy
  • Weak or intermittent spark
  • Unstable ignition output

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