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. This style of stator is also associated with a 9-amp charging configuration, so clean electrical output and connector integrity are especially important. The design priorities are especially important on Force applications where ignition stability depends on clean stator output.

Materials & Build Quality

  • Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
  • 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.
  • Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.

Performance Features

  • Designed for use in wet, hot, and vibration-heavy marine engine compartments.
  • Helps restore ignition charge voltage for strong, repeatable spark output.
  • Helps reduce high-RPM breakup caused by weak or unstable stator output.
  • Provides a dependable electrical source for the ignition system under real-world boating conditions.

Failure Symptoms to Check

  • Random cylinder drop-out
  • Engine misfire under load
  • Poor acceleration caused by weak ignition energy
  • Weak or intermittent spark
  • Spark loss after warm-up

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