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.

Materials & Build Quality

• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
• Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.
• Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.
• The stator body is designed to maintain proper coil alignment under continuous flywheel rotation.

Ignition System Benefits

• Provides a dependable electrical source for the ignition system under real-world boating conditions.
• 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.

Failure Symptoms to Check

• Poor acceleration caused by weak ignition energy
• Random cylinder drop-out
• No-start conditions
• Unstable ignition output
• Weak or intermittent spark

For best results, stator output should be verified with the proper service-manual resistance and DVA voltage tests before installation.
