315783 OMC BOLT

The OMC Johnson/Evinrude 315783 is an OEM starter bolt used to secure the starter motor assembly in Johnson and Evinrude outboard motors and OMC sterndrive engines. This genuine factory fastener ensures the starter is properly positioned and electrically connected for reliable cold-start operation. The bolt is engineered to maintain correct clamping force and prevent fastener loosening under vibration. Replacement with genuine OEM bolts is recommended to ensure proper fit and material specifications. Regular inspection of starter bolts helps prevent starter motor movement that could affect engagement with the flywheel.
