Starter Solenoid for Sea-Doo GTX S 155 1503

This starter solenoid is an electrical relay that engages the starter motor on 2012, 2013, and 2015 Sea-Doo GTX S 155 1503 watercraft, and it is a direct cross-reference for OEM part number 278003012.

Overview

This starter solenoid serves as the high-current switch that delivers battery power to the starter motor on the Sea-Doo GTX S 155 1503. When the start button is pressed, the solenoid closes the circuit and spins the engine for ignition. It is built for riders and mechanics replacing a failed or corroded solenoid on their personal watercraft.

Specs At A Glance

Good To Know

Q: How do I know if my solenoid has failed? A: A common sign is a single loud click from the electrical box with no engine crank when you press start. Testing for voltage at the starter terminal while cranking confirms whether the solenoid is the fault.

Q: Does this solenoid include mounting hardware? A: This is the solenoid unit itself and does not include separate mounting hardware. Reuse the factory fasteners from your original part during installation.

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