Quicksilver Primer Bulbs
When it comes to maintaining reliable fuel delivery for marine engines, Quicksilver has established itself as the OEM gold standard for primer bulbs designed specifically for Mercury, Mariner, and Force outboards. As Mercury Marine's official parts brand, Quicksilver primer bulbs are engineered to meet the exact specifications required for optimal engine performance and longevity.
Ethanol-Compatible Construction for Modern Fuels
Quicksilver primer bulbs are made from materials resistant to today's fuel chemistry, designed to resist hardening and cracking while remaining pliable longer than aftermarket alternatives. The primer bulb construction and materials are compatible with ethanol blended fuels for marine engines, addressing a critical concern for boat owners who have experienced premature failure with older rubber compounds not designed for modern fuel formulations. These bulbs will perform at 5°F after 6 weeks of exposure to fuel, ensuring reliable cold-weather starting even in demanding conditions.
EPA-Certified Low-Permeation Design
Quicksilver offers 2011 EPA certified, low-permeation bulbs with the molded EPA compliance statement "EPA-MERC-PB15", meeting stringent environmental regulations while maintaining the durability boaters depend on. This certification ensures reduced fuel vapor emissions, an increasingly important consideration for marine applications operating in environmentally sensitive areas.
Application-Specific Engineering
Quicksilver Mercury Marine primer bulbs feature a new check valve and ball spring to ensure proper fuel flow, representing the kind of OEM-level engineering refinement that distinguishes genuine replacement parts from generic alternatives. Available for both 5/16" (8mm) and 3/8" fuel line applications, Quicksilver primer bulbs are designed to integrate seamlessly with Mercury and Quicksilver fuel line assemblies. Most models include two hose clamps for secure installation, ensuring leak-free operation under the vibration and pressure cycling typical of marine environments.
Why Choose Quicksilver for Your Marine Fuel System
Whether you're replacing a worn primer bulb assembly or upgrading from an aftermarket component that has failed to meet expectations, Quicksilver primer bulbs deliver the performance and reliability that comes from decades of marine engineering expertise. These components undergo rigorous testing in real-world conditions, ensuring they can withstand the unique challenges of the marine environment—from temperature extremes to constant exposure to fuel and UV radiation. For boat owners committed to maintaining their Mercury, Mariner, or Force outboards with genuine OEM components, Quicksilver primer bulbs represent an essential investment in fuel system integrity and engine reliability.
