Specs At A Glance

Good To Know

Q: How do I know if the solenoid rather than the starter is at fault? A: A clicking sound with no crank often points to the solenoid, while a completely silent start can indicate the starter or battery. Testing voltage at the solenoid terminals confirms which component has failed.

Q: Is this solenoid safe to use in a wet marine environment? A: The sealed housing is designed to resist splash and humidity typical of jet boat engine compartments. Keep the mounting position and wiring connections dry and secure for best long-term results.

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