Sierra 118-5890-1 Shift Assist Module Kit Marine Outboard

The Sierra 118-5890-1 Shift Assist Module Kit is a quality replacement electrical component designed for marine engines. The shift assist module works in conjunction with the ignition system to momentarily retard ignition timing during gear engagement, reducing the shock load on the drivetrain when shifting into forward or reverse. This results in smoother, quieter shifts and reduced wear on the gearcase and shift components.
