Specs At A Glance

Good To Know

Q: How do I know if my solenoid has failed? A: A single click or silence when you press start, often with good battery voltage, points to a failed solenoid. You can also test for voltage at the starter terminal while cranking.

Q: Is this an original Sea-Doo part? A: This is an aftermarket starter solenoid made as a cross-reference replacement for OEM 278003012. It is not an original Sea-Doo product.

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