Sierra Power Pack 18-5761-1 for Evinrude 2.5, 2.6L Outboards (1986-88)

The Sierra Power Pack 18-5761-1 is an ignition power pack designed for Evinrude outboard motors, built to deliver the spark energy needed for reliable engine starting and running performance. A power pack is a core ignition component that stores and discharges electrical energy to fire the spark plugs at the correct timing, and a failing or weak unit is a common cause of hard starting, misfiring, or a no-spark condition on affected outboards.

This power pack is manufactured for Evinrude 2.5 and 2.6L outboard engines built in 1986-88. It is sold as a direct-fit ignition component intended to restore factory ignition performance on these specific engines.
