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.

Construction Details

• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
• Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.
• Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
• Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.

Key Functional Details

• Helps reduce high-RPM breakup caused by weak or unstable stator output.
• Designed to maintain stable voltage as engine load and RPM change.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Supports smooth acceleration by helping the ignition system maintain consistent energy.

Failure Symptoms to Check

• Spark loss after warm-up
• Weak or intermittent spark
• Hard starting
• No-start conditions
• Unstable ignition output

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