Product Details

A properly functioning stator is critical to reliable spark production, and this assembly is built to deliver steady voltage under demanding marine operating conditions. 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

  • Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.
  • Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.
  • Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
  • The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.

Performance Features

  • Engineered to meet OEM-style electrical output characteristics.
  • Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
  • Helps restore ignition charge voltage for strong, repeatable spark output.
  • Helps reduce high-RPM breakup caused by weak or unstable stator output.

Failure Symptoms to Check

  • High-rpm breakup
  • Poor acceleration caused by weak ignition energy
  • Hard starting
  • Charging output problems where the stator also supports charging circuits
  • Engine misfire under load

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