Product Details

This replacement stator is designed for stable output and long service life in harsh outboard environments where heat, moisture, and vibration are constant concerns. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Construction Details

  • The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.
  • Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.
  • The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
  • Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.

Performance Features

  • Helps reduce high-RPM breakup caused by weak or unstable stator output.
  • Designed to maintain stable voltage as engine load and RPM change.
  • Supports smooth acceleration by helping the ignition system maintain consistent energy.
  • Engineered to meet OEM-style electrical output characteristics.

Common Ignition Symptoms

  • Poor acceleration caused by weak ignition energy
  • No-start conditions
  • Charging output problems where the stator also supports charging circuits
  • Engine misfire under load
  • Random cylinder drop-out

Clean grounds, sound connectors, and correct flywheel condition are important for reliable stator performance after replacement.
