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.

Design & Materials

  • High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
  • Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
  • The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
  • The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.

Performance Features

  • Provides a dependable electrical source for the ignition system under real-world boating conditions.
  • Helps restore ignition charge voltage for strong, repeatable spark output.
  • Engineered to meet OEM-style electrical output characteristics.
  • Helps correct intermittent spark loss caused by heat-sensitive stator windings.

Common Symptoms of Stator Failure

  • Spark loss after warm-up
  • Weak or intermittent spark
  • Hard starting
  • Random cylinder drop-out
  • High-rpm breakup

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