Sierra 18-5763-1 Power Pack, Evinrude/Johnson Replacement for 582285, 583170, 586800

The Sierra 18-5763-1 Power Pack is an ignition power pack built to meet or exceed the performance of the original equipment unit it replaces on Evinrude/Johnson outboard motors. The power pack is a core component of the outboard's ignition system, controlling the timing and delivery of spark to the engine's cylinders, and a failing or worn power pack commonly shows up as hard starting, misfiring, stalling, or a loss of power at higher RPM. Replacing it with the Sierra 18-5763-1 restores reliable ignition performance without the expense of chasing individual ignition components.

This power pack is a direct fit across a range of Evinrude/Johnson outboard horsepower ratings and model years, making it a straightforward drop-in replacement for boaters maintaining older Evinrude/Johnson power heads. It is interchangeable with several commonly referenced OEM and aftermarket part numbers, so it can be used to replace units originally sold under those numbers as well.
