Sierra 18-5814 Solenoid, Replaces 581528 and 172869, for Evinrude Outboard Motors

The Sierra 18-5814 is a marine starter solenoid built as a direct replacement for outboard motor electrical systems. It uses an isolated base design and features a machined exterior finish for durability in the marine environment. This solenoid is commonly used on Evinrude outboard motors and is engineered to restore reliable starter engagement when the original solenoid fails or wears out. The unit measures 6 x 2.75 x 6 inches and weighs 0.29 pounds, making it a compact, drop-in style component for outboard electrical repairs. Its white housing and isolated base configuration are consistent with the original equipment design it is built to replace. As a Sierra part, it is manufactured to cross-reference directly against the OEM numbers 581528 and 172869, giving boat owners and marine technicians a straightforward way to source a correct replacement without needing to track down a discontinued original part. This solenoid is a core component in the outboard's starting circuit, transferring high current from the battery to the starter motor when the ignition switch is engaged, and a failed solenoid is a common cause of a no-start condition even when the battery and starter motor are otherwise healthy.
