Parts Desk Insights
This starter is the correct choice for OMC 3-cylinder 55–75 HP motors that are slow to crank or won't engage at all. Before ordering, confirm whether your existing starter uses a 1-piece or 2-piece drive assembly — older OMC outboards used a 1-piece design, while later models use a 2-piece. The drive assembly type affects compatibility, so check your current unit before purchasing a replacement drive. If you're also sourcing a solenoid, see the Sierra Starter Solenoid for Johnson / Evinrude. For other OMC starter applications, browse the ARCO 57-5376 for Johnson / Evinrude OMC, the ARCO 5386 for OMC (1985+), or the ARCO 5389 for OMC 25–50 HP 2-Cylinder.
