Sierra 18-5772-2 Power Pack for Evinrude Outboard Motors

The Sierra 18-5772-2 Power Pack is an ignition power pack built for Evinrude outboard motors. As part of Sierra's outboard ignition component line, it supplies the switching function the engine's ignition system needs to fire properly, and it is designed and sold as a direct component replacement in the Evinrude Outboard Power Packs category. Sierra manufactures its ignition parts to marine-duty standards so they hold up to the vibration, heat cycling, and moisture exposure typical of an outboard engine compartment.

Each unit weighs 2.17 pounds and ships as a single power pack (order the quantity your engine calls for; some outboard ignition systems require more than one power pack per engine). Always confirm the part number stamped on your engine's original power pack, or check it against your engine's serial number range, before ordering to ensure correct fitment.
