Product Details

This replacement stator is designed to support stable ignition output by converting flywheel rotation into controlled electrical energy for the ignition circuit. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Construction Details

  • Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
  • Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.
  • 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.

Key Functional Details

  • Designed for use in wet, hot, and vibration-heavy marine engine compartments.
  • Supports dependable starting by delivering the voltage needed by the ignition module.
  • Engineered to meet OEM-style electrical output characteristics.
  • Supports smooth acceleration by helping the ignition system maintain consistent energy.

Problems a Weak Stator Can Cause

  • Weak or intermittent spark
  • Random cylinder drop-out
  • Unstable ignition output
  • Engine misfire under load
  • Poor acceleration caused by weak ignition energy

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