Built for outboard ignition service, this stator supplies the charging voltage used by the ignition system while helping maintain consistent spark energy through the RPM range. The design priorities are especially important on Yamaha applications where ignition stability depends on clean stator output.

Construction Details

• Precision-wound copper coils are used to promote efficient voltage generation and stable output.
• 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

• Supports smooth acceleration by helping the ignition system maintain consistent energy.
• Designed to maintain stable voltage as engine load and RPM change.
• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
• Supports dependable starting by delivering the voltage needed by the ignition module.

Common Ignition Symptoms

• Weak or intermittent spark
• No-start conditions
• Charging output problems where the stator also supports charging circuits
• Hard starting
• Engine misfire under load

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