🔌 Function

The ignition stator generates electrical output under the flywheel for the outboard ignition system. It provides the energy required for spark generation during cranking and running.

Common signs of failure:

• Weak or missing spark

• Hard starting

• Engine cuts out once warm

• Misfire under throttle

• Intermittent spark caused by heat or vibration

• Damaged or brittle stator leads

• Burnt stator winding or cracked insulation

• Stator resistance or output below specification

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
