Sierra 18-5768-1 Power Pack, Replaces Evinrude/Johnson 584908, Fits 20-28 HP Outboards 1993-2001

The Sierra 18-5768-1 Power Pack is a direct-fit ignition module built to meet or exceed the original equipment part it replaces on Evinrude and Johnson outboards. Constructed with an aluminum and stainless steel housing in a white finish, it is designed as a transom-mount component that controls ignition timing and spark delivery for reliable engine starting and running performance. This Power Pack is engineered as a straightforward replacement for outboards that have lost spark or are experiencing ignition-related running issues, restoring the engine to proper operating condition without modification to the original wiring or mounting points.

Fitment covers 20, 25, and 28 horsepower Evinrude/Johnson outboards across the 1993-95 and 1996-01 model years, as detailed in the fitment table below. Because ignition components vary by horsepower and model year, confirm your engine's horsepower and year against the fitment list before ordering to ensure the 18-5768-1 is the correct part for your outboard. The unit is a single-count component and ships ready to install as a one-for-one replacement for the OEM power pack.
