Starter Solenoid for Yamaha

This starter solenoid is a direct replacement for the factory relay that switches high current to the starter motor on Yamaha 242 LTD S 1800 boats, and it carries OEM cross-reference 1B7-81940-00-00.

Overview

This starter solenoid for Yamaha is the relay that closes the battery-to-starter circuit with a low-current signal from the ignition switch. For owners of a 242 LTD S 1800, it restores the solenoid function when the engine will not crank or the relay clicks without engaging the motor. Replace it whenever the original part fails, sticks, or draws excess current during starting.

Good To Know

Q: How do I know the solenoid is the problem? A: A single click or silence when turning the key, with good battery voltage, usually points to a failed solenoid rather than the starter itself.

Q: Does this come with mounting hardware? A: Only what is shown is shipped, so reuse the original fasteners from your Yamaha's starter solenoid unless otherwise stated.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
