Good To Know

Q: How do I know if my starter solenoid has failed? A: A single loud click with no engine crank, or no response at all when pressing start, usually points to a failed solenoid. Testing for voltage at the starter terminal while cranking confirms the diagnosis.

Q: Is this solenoid a direct replacement for 278003012? A: Yes, it is built to replace that OEM part number on compatible Sea-Doo models. Confirm your model and serial number before ordering.

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