Good To Know

Q: How do I know the solenoid is failing? A: A single loud click with no crank, or no response at all when the start button is pressed, often points to a failed solenoid. Testing for voltage at the starter terminal while cranking confirms it.

Q: Is this an original Sea-Doo part? A: This is an aftermarket starter solenoid built to cross-reference 278003012 for Sea-Doo applications. It is not an original brand product.

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