This stator assembly is built to help the ignition system maintain clean spark delivery by supplying consistent electrical output as the flywheel rotates. The design priorities are especially important on Yamaha applications where ignition stability depends on clean stator output.

Stator Design

• Heavy-duty winding insulation helps prevent shorting between coil layers during extended operation.
• Epoxy encapsulation helps shield internal windings from moisture, vibration, and corrosion.
• Laminated core sections help concentrate magnetic flux from the flywheel magnets for reliable electrical production.
• High-temperature insulation helps protect the windings from heat cycling inside the engine cowling.

Operating Features

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

Common Ignition Symptoms

• Charging output problems where the stator also supports charging circuits
• Weak or intermittent spark
• Poor acceleration caused by weak ignition energy
• High-rpm breakup
• Unstable ignition output

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