The stator acts as the electrical foundation of the ignition system, producing the current needed to feed the ignition module and support consistent firing. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Stator Design

• Marine-grade lead wires and molded connectors help maintain dependable contact in a high-vibration environment.
• Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
• The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.
• Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.

Performance Features

• 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 correct intermittent spark loss caused by heat-sensitive stator windings.
• Helps restore ignition charge voltage for strong, repeatable spark output.

Common Symptoms of Stator Failure

• No-start conditions
• Spark loss after warm-up
• High-rpm breakup
• Poor acceleration caused by weak ignition energy
• Engine misfire under load

Clean grounds, sound connectors, and correct flywheel condition are important for reliable stator performance after replacement.
