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.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.
• Sealed construction helps reduce moisture intrusion that can lead to weak spark or no-spark conditions.
• Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.

Key Functional Details

• Engineered to meet OEM-style electrical output characteristics.
• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
• Helps reduce high-RPM breakup caused by weak or unstable stator output.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.

Common Symptoms of Stator Failure

• Poor acceleration caused by weak ignition energy
• Hard starting
• Spark loss after warm-up
• No-start conditions
• High-rpm breakup

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