Sierra Outboard Starter 18-5628, Replaces OMC 586285, Fits Johnson/Evinrude 120-140 HP 1985-94 and 130 HP 1995-99

The Sierra 18-5628 is an outboard starter motor built for Johnson/Evinrude (OMC/BRP) outboards, matched to the original equipment 586285 starter it replaces. It is designed as a direct fit for two fitment windows: 120 thru 140 HP outboards from 1985-94, and 130 HP outboards from 1995-99. The starter uses an NSS-spec starter drive paired with a compatible 18-5679 drive assembly (O.E. 586100) featuring a 10-tooth drive gear, and it works with the Sierra 18-5697 drive brush kit (O.E. 385952) for brush service and rebuilds. Because the drive assembly and brush kit are sold as separate part numbers, buyers doing a full rebuild should order those alongside the starter itself rather than assuming they are included.

This starter is intended as a bolt-on replacement for the listed Johnson/Evinrude outboard applications, restoring cranking power without modification to the outboard's electrical system. It ships at 7.46 pounds and measures 6 x 9.63 x 4.5 inches, with a 1.4 KW output rating.
