A properly functioning stator is critical to reliable spark production, and this assembly is built to deliver steady voltage under demanding marine operating conditions. The design priorities are especially important on Johnson/Evinrude applications where ignition stability depends on clean stator output.

Stator Design

• Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
• Precision-wound copper coils are used to promote efficient voltage generation and stable output.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.

Key Functional Details

• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Designed for use in wet, hot, and vibration-heavy marine engine compartments.
• Supports smooth acceleration by helping the ignition system maintain consistent energy.
• Designed to maintain stable voltage as engine load and RPM change.

Problems a Weak Stator Can Cause

• Poor acceleration caused by weak ignition energy
• High-rpm breakup
• Weak or intermittent spark
• Engine misfire under load
• Spark loss after warm-up

Always compare resistance and peak-voltage readings to the correct service specifications when diagnosing a suspected stator failure.
