Sierra Stator 18-5878-1 for Johnson/Evinrude 150 and 175 HP Outboards (1993-2006)

The Sierra 18-5878-1 Stator is a replacement ignition stator engineered for Johnson/Evinrude outboard motors, supplying the charging current the ignition system needs to fire consistently under load. Built to meet or exceed the performance of the original equipment part it replaces, this stator is designed for the harsh marine operating environment, standing up to vibration, heat cycling, and moisture exposure that shorten the life of lower-quality components.

This stator is intended as a direct fitment replacement for Johnson/Evinrude 150 HP and 175 HP outboard motors covering model years 1993 through 2006. It is sold as a single unit and installs in place of the original stator using standard outboard powerhead disassembly procedures. As with all Sierra parts, it is backed by Sierra's standard limited warranty, giving boat owners and marine technicians confidence when restoring ignition output on an aging outboard.
