Product Details

Designed for marine CDI systems, this stator helps produce the charge voltage required for strong spark output and reliable combustion control. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Design & Materials

  • The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
  • High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
  • Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.
  • Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.

Ignition System Benefits

  • Engineered to meet OEM-style electrical output characteristics.
  • Designed to maintain stable voltage as engine load and RPM change.
  • Supports smooth acceleration by helping the ignition system maintain consistent energy.
  • Helps correct intermittent spark loss caused by heat-sensitive stator windings.

Common Ignition Symptoms

  • No-start conditions
  • High-rpm breakup
  • Weak or intermittent spark
  • Charging output problems where the stator also supports charging circuits
  • Poor acceleration caused by weak ignition energy

Because stator failure can mimic other ignition problems, testing the trigger, coils, switch box or power pack, and related grounds is recommended.
