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.

Design & Materials

• Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.
• 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.

Operating Features

• Provides a dependable electrical source for the ignition system under real-world boating conditions.
• Helps reduce high-RPM breakup caused by weak or unstable stator output.
• Designed for use in wet, hot, and vibration-heavy marine engine compartments.
• Designed to maintain stable voltage as engine load and RPM change.

Problems a Weak Stator Can Cause

• High-rpm breakup
• Weak or intermittent spark
• Charging output problems where the stator also supports charging circuits
• No-start conditions
• Poor acceleration caused by weak ignition energy

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