Specs At A Glance

Good To Know

Q: What causes a starter solenoid to fail on a personal watercraft? A: Corrosion, heat cycling, and repeated high-current starts wear the internal contacts until they no longer pass enough current. A failed unit usually clicks once without turning the engine over.

Q: Can I install this solenoid myself? A: Yes, it mounts at the factory location and connects using the standard wiring terminals. Disconnect the battery first and confirm the part number matches before starting.

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