Throttle Return Springs

The QUICKCAR Racing Products Throttle Return Springs (Part No. 64-169) is a chrome-plated steel spring pair engineered to restore reliable throttle control in high-performance marine engines. These return springs ensure the throttle linkage returns smoothly to idle position after acceleration, a critical safety function for boat operators working in demanding offshore and freshwater conditions.

Built from hardened steel with chrome plating, this throttle return spring pair resists corrosion from saltwater spray and humidity—common failure points on boats exposed to marine environments. The dual-spring configuration provides redundant tension control, preventing throttle sticking or creep during operation. Proper spring tension is essential for throttle response accuracy and engine idle stability, particularly in rough water where sensitive throttle input directly affects boat handling and fuel efficiency.

This throttle return spring pair is ideal for owners maintaining or rebuilding carbureted marine engines, ski boats, fishing vessels, and performance watercraft where original springs have fatigued or corroded. QUICKCAR Racing Products springs are commonly specified by marine technicians and weekend mechanics restoring vintage outboards, inboards, and sterndrive systems. Weekend anglers and serious offshore fishermen alike depend on functional throttle linkage for safe boat operation in variable water conditions.

When upgrading or replacing worn throttle components, ensuring proper spring tension prevents hesitation during acceleration and maintains consistent idle speed—both factors that improve safety and engine longevity on the water. Stock these replacement springs for routine marine engine maintenance and restoration projects.
