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 Mercury/Mariner applications where ignition stability depends on clean stator output.

Design & Materials

• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
• The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.
• Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
• Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.

Key Functional Details

• Helps reduce high-RPM breakup caused by weak or unstable stator output.
• Helps restore ignition charge voltage for strong, repeatable spark output.
• Designed to maintain stable voltage as engine load and RPM change.
• Supports dependable starting by delivering the voltage needed by the ignition module.

Common Symptoms of Stator Failure

• Engine misfire under load
• Weak or intermittent spark
• Spark loss after warm-up
• Random cylinder drop-out
• No-start conditions

A stator should be diagnosed as part of the complete ignition system so related components are not overlooked.
