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. This style of stator is also associated with a 9-amp charging configuration, so clean electrical output and connector integrity are especially important. The design priorities are especially important on Force applications where ignition stability depends on clean stator output.

Design & Materials

  • Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.
  • Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
  • 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.

Performance Features

  • Supports smooth acceleration by helping the ignition system maintain consistent energy.
  • Helps reduce high-RPM breakup caused by weak or unstable stator output.
  • Designed for use in wet, hot, and vibration-heavy marine engine compartments.
  • Engineered to meet OEM-style electrical output characteristics.

Common Symptoms of Stator Failure

  • Unstable ignition output
  • Hard starting
  • Weak or intermittent spark
  • Spark loss after warm-up
  • Charging output problems where the stator also supports charging circuits

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