Industrial 985063 12-Volt Solenoid Assembly

The ARCO SW268 12-Volt Solenoid Assembly is a genuine, original-equipment-quality replacement solenoid designed for BRP-OMC outboard engines. This 12-volt unit uses a grounded-base design and directly replaces BRP-OMC parts 584128, 981410, 982187, and 985063, as well as Sierra equivalents 18-5812 and 18-5813, offering a drop-in substitute for the OEM solenoid in the starting circuit. It is marketed by ARCO Marine as a replacement for BRP-OMC applications and is commonly used to restore reliable starter engagement on legacy OMC/BRP outboards. The SW268 is widely stocked by marine parts retailers and aligns with BRP-OMC cross-references, ensuring compatibility with boats that previously used the noted part numbers. In practice, installers replace a worn or failing solenoid to eliminate slow or no-start symptoms and to maintain consistent engagement of the starter motor in 12-volt electrical systems aboard BRP-OMC-powered vessels.
