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

• 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.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.

Operating Features

• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
• Designed to maintain stable voltage as engine load and RPM change.
• Helps reduce high-RPM breakup caused by weak or unstable stator output.
• Provides a dependable electrical source for the ignition system under real-world boating conditions.

Problems a Weak Stator Can Cause

• Unstable ignition output
• High-rpm breakup
• Weak or intermittent spark
• Hard starting
• Engine misfire under load

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