The Sierra 18-5837 is a starter solenoid built for standard rotation, clockwise-turning marine engines. It is the correct replacement solenoid for 1986-1992 GM V-6 and V-8 sterndrive engines and 1990-1993 OMC King Cobra applications, and it directly replaces OEM numbers 984456 and 986505. The solenoid mounts using an offset bolt pattern and carries SAE J1171 ignition protection certification, meeting the marine industry standard for spark suppression around fuel vapors.

Built with a machined exterior housing rated at 1.4 KW, the 18-5837 is sized to fit the same footprint as the original equipment part it replaces, making it a straightforward swap for a failed or corroded solenoid. This is a common wear item on OMC Sterndrive and OMC Cobra starter systems, and keeping a correct-fit replacement on hand avoids downtime when the original solenoid fails to engage the starter.
