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.

Construction Details

• 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.
• Precision-wound copper coils are used to promote efficient voltage generation and stable output.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.

Operating Features

• Supports dependable starting by delivering the voltage needed by the ignition module.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Designed for use in wet, hot, and vibration-heavy marine engine compartments.
• Supports smooth acceleration by helping the ignition system maintain consistent energy.

Failure Symptoms to Check

• Unstable ignition output
• Spark loss after warm-up
• Charging output problems where the stator also supports charging circuits
• Engine misfire under load
• High-rpm breakup

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