Built for outboard ignition service, this stator supplies the charging voltage used by the ignition system while helping maintain consistent spark energy through the RPM range. The design priorities are especially important on Mercury/Mariner applications where ignition stability depends on clean stator output.

Stator Design

• The coil assembly is built to resist breakdown from heat, oil mist, humidity, and repeated thermal expansion.
• Vibration-resistant construction helps reduce the chance of intermittent output caused by loose or damaged windings.
• 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.

Operating Features

• Designed to maintain stable voltage as engine load and RPM change.
• Helps the ignition system recover from weak output, hard starting, and cylinder drop-out symptoms.
• Helps correct intermittent spark loss caused by heat-sensitive stator windings.
• Helps restore ignition charge voltage for strong, repeatable spark output.

Failure Symptoms to Check

• Unstable ignition output
• Poor acceleration caused by weak ignition energy
• No-start conditions
• Charging output problems where the stator also supports charging circuits
• Spark loss after warm-up

Because stator failure can mimic other ignition problems, testing the trigger, coils, switch box or power pack, and related grounds is recommended.
