Sierra 18-5679 Drive Assembly - Replaces OMC 585267 586100 - for 9.9/15 HP Evinrude Outboards 1997 & Up

The Sierra 18-5679 Drive Assembly is a starter drive assembly built for outboard motors, designed as a direct replacement for the OMC drive assembly used on 9.9/15 HP Evinrude 4-stroke outboards from 1997 and up. The drive assembly is the component that engages the starter motor with the flywheel to turn the engine over during starting; it is constructed of steel and features a 10-tooth drive gear that matches the original equipment tooth count for proper engagement with the flywheel ring gear.

Sierra manufactures this drive assembly to match OEM specifications, making it a straightforward swap for a worn, stripped, or non-engaging drive assembly on covered applications. It pairs with the Sierra 18-5697 Drive Brush Kit for a complete starter service. Each unit measures 3.25 x 3.25 x 1.5 inches and weighs 0.32 pounds.
