Product Details

Designed as a key charging source for the ignition circuit, this stator helps provide the electrical energy needed for smooth throttle response and dependable starting. The design priorities are especially important on Johnson/Evinrude applications where ignition stability depends on clean stator output.

Stator Design

  • Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.
  • Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.
  • Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
  • Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.

Performance Features

  • Helps correct intermittent spark loss caused by heat-sensitive stator windings.
  • Provides a dependable electrical source for the ignition system under real-world boating conditions.
  • Engineered to meet OEM-style electrical output characteristics.
  • Supports smooth acceleration by helping the ignition system maintain consistent energy.

Common Ignition Symptoms

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

For best results, stator output should be verified with the proper service-manual resistance and DVA voltage tests before installation.
