This replacement stator is designed for stable output and long service life in harsh outboard environments where heat, moisture, and vibration are constant concerns. 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.
• Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.

Key Functional Details

• Provides a dependable electrical source for the ignition system under real-world boating conditions.
• Helps reduce high-RPM breakup caused by weak or unstable stator output.
• Designed to maintain stable voltage as engine load and RPM change.
• Helps restore ignition charge voltage for strong, repeatable spark output.

Common Ignition Symptoms

• Hard starting
• High-rpm breakup
• Weak or intermittent spark
• Spark loss after warm-up
• Engine misfire under load

Always compare resistance and peak-voltage readings to the correct service specifications when diagnosing a suspected stator failure.
