💡 What is a 12V starter solenoid used for in marine outboard engines?

In simple terms, it acts as a high-current switch that energizes the starter motor when the ignition is engaged.

• Hard-wires ignition switch to the starter motor to handle heavy current
• Provides quick engagement and protects the ignition switch from surge
• Built with copper windings and robust contacts for reliable operation
• Marine-grade design with isolated base helps resist humidity and corrosion
