Sierra 18-5853 Starter Solenoid for Yamaha Outboards, Replaces 6E5-81941-10-00 / 6E5-81941-11-00

The Sierra 18-5853 Starter Solenoid is a replacement electrical component that engages the starter motor on compatible Yamaha outboard engines. When the ignition key or start switch is activated, the solenoid closes the high-current circuit between the battery and the starter motor, allowing the engine to crank. A failed or worn solenoid is a common cause of a no-crank condition even when the battery and starter motor themselves are in good working order, so replacing it with a properly matched unit like the 18-5853 restores reliable starting.

This solenoid is built to Sierra's marine specifications so it can stand up to the vibration, heat, and moisture exposure typical of an outboard engine compartment, and it is designed to meet or exceed the performance of the original equipment Yamaha solenoid it replaces. It is rated at 1.4 KW and is sold as a single unit (1.0 count) ready to install in place of the original part.
