Sierra 18-5864-1 Stator for Mercury 35 HP 2-Cylinder Outboard, Replaces Mercury Marine 86617A20

The Sierra 18-5864-1 stator is a replacement charging-system component built for Mercury 35 HP 2-cylinder outboard engines falling within serial numbers 6445653 through B110788. The stator is the stationary winding assembly that generates AC current as the flywheel rotates past it, supplying the engine's charging and ignition systems; a worn or failed stator is a common cause of no-charge conditions, erratic tachometer readings, or ignition misfires on these outboards. This unit is a direct equivalent to Mercury Marine part number 86617A20, allowing it to install in place of the original component without modification. Construction is aluminum, finished in white to match factory outboard powerhead colors, and the stator is designed as an engine-mount component that installs onto the powerhead using the existing mounting points. It is engineered for 4-stroke, gasoline-fueled outboard applications and is built to meet the performance specifications of the original equipment part it replaces. Each stator ships as a single unit and is backed by Sierra's warranty coverage. Boat owners and marine technicians use this part when diagnosing charging or ignition faults on the applicable Mercury 35 HP 2-cylinder outboard engines, and it is sold as a like-for-like replacement for the original stator fitted at the factory.
