The stator acts as the electrical foundation of the ignition system, producing the current needed to feed the ignition module and support consistent firing. The design priorities are especially important on Johnson/Evinrude applications where ignition stability depends on clean stator output.

Design & Materials

• 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.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
• Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.

Operating Features

• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
• Engineered to meet OEM-style electrical output characteristics.
• Helps reduce high-RPM breakup caused by weak or unstable stator output.

Common Symptoms of Stator Failure

• Spark loss after warm-up
• No-start conditions
• Charging output problems where the stator also supports charging circuits
• Poor acceleration caused by weak ignition energy
• Engine misfire under load

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