Quicksilver 18458Q4 Water Separating Fuel Filter Kit with Blue Sensor

The Quicksilver 18458Q4 is a complete water separating fuel filter replacement kit designed specifically for 1996 and newer Mercury and Mariner V6 EFI outboard engines. This genuine OEM replacement kit includes a 10-micron canister filter element with O-ring and an integrated blue plastic water warning sensor unit that alerts you when water accumulates in the fuel system.

Key Features:

• 10-micron filtration removes harmful contaminants, particles, and water from fuel before reaching your engine
• Includes blue screw-in water warning sensor for early detection of fuel contamination
• Internal epoxy coating and corrosion-resistant external paint for superior weather resistance in marine environments
• Complete replacement kit with filter element, O-ring, and sensor unit
• Manufactured to Mercury Marine OEM specifications for guaranteed fit and performance

Regular maintenance is critical for fuel system performance. Replace this filter annually during winterization or every 100 hours of engine operation, whichever comes first. Consult your owner's manual for specific inspection and replacement schedules. Quicksilver has provided trusted marine engine parts and accessories for over 65 years, delivering the quality and reliability that Mercury and Mariner outboard owners depend on.
