Product Details

This marine stator assembly is engineered to generate the electrical energy needed for dependable CDI ignition performance across changing engine speeds. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Materials & Build Quality

  • Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
  • Precision-wound copper coils are used to promote efficient voltage generation and stable output.
  • Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.
  • The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.

Ignition System Benefits

  • Helps reduce high-RPM breakup caused by weak or unstable stator output.
  • Designed to maintain stable voltage as engine load and RPM change.
  • Designed for use in wet, hot, and vibration-heavy marine engine compartments.
  • Engineered to meet OEM-style electrical output characteristics.

Problems a Weak Stator Can Cause

  • Unstable ignition output
  • Weak or intermittent spark
  • Hard starting
  • High-rpm breakup
  • Spark loss after warm-up

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