Product Details

Engineered for reliable marine ignition operation, this stator helps restore proper voltage generation when the original assembly becomes weak, heat-sensitive, or unstable. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Design & Materials

  • Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.
  • Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.
  • 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.

Ignition System Benefits

  • Engineered to meet OEM-style electrical output characteristics.
  • Designed to maintain stable voltage as engine load and RPM change.
  • Helps restore ignition charge voltage for strong, repeatable spark output.
  • Supports dependable starting by delivering the voltage needed by the ignition module.

Common Symptoms of Stator Failure

  • Unstable ignition output
  • Hard starting
  • No-start conditions
  • Weak or intermittent spark
  • Engine misfire under load

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