Sierra Stator 18-99227 - Replaces 584292 - Johnson/Evinrude 150-175 HP Cross Flow 1989-1992

The Sierra Stator 18-99227 is a 6-cylinder, 35 Amp charging component built to restore reliable electrical output on Johnson/Evinrude Cross Flow outboards equipped with Quick Start and S.L.O.W. This stator generates the AC current the engine's rectifier converts into usable charging power, making it a core part of the ignition and charging circuit on covered powerheads. It is designed as a direct fit for the specified Johnson/Evinrude 150, 155, and 175 HP Cross Flow engines built for the 1989-1992 model years, replacing the original stator when output weakens, windings fail, or the engine shows erratic charging or no-spark symptoms tied to the charging system.

Installation follows the standard stator replacement procedure for these Cross Flow powerheads: the flywheel is removed to access the stator plate, the old unit is unbolted and disconnected, and the Sierra 18-99227 is bolted in and wired in its place. Because charging and ignition timing on these engines depend on a correctly functioning stator, using a properly rated 35 Amp unit matched to the 6-cylinder Cross Flow configuration helps avoid undercharging or intermittent electrical faults.
