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

Design & Materials

• Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.
• Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.

Key Functional Details

• Supports dependable starting by delivering the voltage needed by the ignition module.
• Helps reduce high-RPM breakup caused by weak or unstable stator output.
• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.

Common Ignition Symptoms

• No-start conditions
• Poor acceleration caused by weak ignition energy
• Weak or intermittent spark
• Engine misfire under load
• Random cylinder drop-out

A stator should be diagnosed as part of the complete ignition system so related components are not overlooked.
