Sierra Stator Converter 18-99318, 5-Cylinder, for Chrysler, Force, Sears and Gamefisher Outboards

The Sierra 18-99318 is a stator converter built for 5-cylinder outboard powerheads, replacing the ignition charging component that supplies AC current to the engine's rectifier and charging system. As the stator ages or its windings degrade, engines can experience weak spark, charging failures, or a no-start condition, so this converter restores reliable power delivery for engines that rely on this configuration. It is designed for 5-cylinder outboards sold under the Chrysler, Force, Sears, and Gamefisher brands, reflecting how these outboard lines shared common powerhead architecture and electrical components. The stator converter is a single-unit replacement, making it a straightforward swap for technicians and boat owners replacing a failed or worn charging component. It ships as one item ready for installation into the compatible 5-cylinder powerhead. Because ignition and charging components directly affect engine starting and running reliability, this stator converter is a maintenance item worth keeping in reserve when servicing older Chrysler, Force, Sears, or Gamefisher outboards with 5-cylinder engines.
