Parts Desk Insights
The 57-30457 is the right choice when your inboard engine requires counter-clockwise (CCW) rotation — a detail that’s easy to overlook but critical to get right. Confirm your engine’s rotation direction before ordering. If your application calls for clockwise (CW) rotation, see the ARCO 57-30456 High Performance Starter (CW Rotation) instead. For a standard-duty alternative on GM inboards, the ARCO 57-30433 Gear Reduction Starter is a cost-effective option. For the highest-torque inboard starting solution available, consider the ARCO 30470A Hi-Torque Gear Reduction Starter. Complete your starting system refresh with the ARCO Heavy-Duty Starter Solenoid (SW463) and the ARCO Starter Mounting Bolt Kit (57-MBK450) for a clean, rattle-free installation.
